Unit non-response has been recognized as a potential problem because it may cause the bias in the inference of important parameters. In this research, we investigate the non-response bias in Contingent Valuation (CV) by using Inverse Probability Weighting (IPW). In the application of IPW, however, one of the major problem is the inaccessibility to auxiliary variables. We could deal with this inaccessibility problem when we use internet-based research because it is available that the individual information registered to the internet research company as auxiliary variables. We apply IPW to evaluate consumers' willingness to pay for a grass-fed beef stake produced by environmentally friendly farming system.

The result in the logistic regression of the response propensity shows that response propensity have the relation to personal income, age, characteristics of family member, use of SNS or video distribution websites, and hobbies. On the other hand, there is almost no difference between the respondents’ mean of WTP and population mean of WTP estimated by IPW. From this survey, there is no evidence that these differences in auxiliary variables between respondents and non-respondent cause non-respondent bias in the estimation of consumers’ WTP for a grass-fed beef.

Home composting (HC) has become an increasingly important consideration in the framework of sustainable municipal organic waste (MOW) management in developing countries. We develop, for the first time, two HC behavior models, which include households’ decisions to participate in a HC scheme and the level of HC participation. By applying Logit and Ordered logit models, a survey of 202 respondents in rural areas of Hoi An, Vietnam, indicates that households’ decisions to get involved in a HC scheme and the level of HC participation are affected by motivational factors such as knowledge about HC, attitude toward it, and owning a garden. We then explore the differences between the influencing factors for the two models. Interestingly, while participation in the HC training program influence the decision to participate in the HC scheme, the factor appears unimportant in increasing the level of HC practice. In addition, once the HC participation decision has been made, we find that pro-environmental behavior (such as habit of reusing plastic bags and reducing wastefulness) could promote a higher level of HC practice. These findings could help policy makers in promoting HC behavior to enhance a sustainable MOW management strategy at the household level.

Most recent municipal organic waste-separation at source (MOW-SAS) programs that have been introduced in developing countries remain pilot programs, but have not fully developed into sustainable municipal solid-waste management strategies. The city of Hoi An, Vietnam, implemented a mandatory MOW-SAS program in 2012. Using Structural Equation Modeling, this study investigates the psychological driving forces behind households’ behaviors toward the MOW-SAS program. This study finds that moral norm (moral perception of what is good or bad), attitude toward sorted waste, and situational factors (issues concerning physically sorting garbage, such as time, space, and lack of family cooperation) can significantly affect household behaviors toward MOW-SAS. It confirms the need for supplying frequent environmental educational campaigns and highlighting the benefits of MOW-SAS programs. Moreover, the study finds that households’ system trust in local authority concerning the MOW-SAS program is an important driving force behind the behavior. Therefore, recommendation is also made on the need to develop strong leadership in local authorities through improving: (1) reliability (ability to effectively treat sorted waste), (2) legitimacy (punitive measures for non-participants), and (3) effectiveness (dissemination of information about the benefits of MOW-SAS programs) for promoting MOW-SAS.

This study explores the relationship between China’s food imports and the ecological environment (mainly agricultural carbon emissions) of its trading partners. Using panel data from 15 major food trading partners from 2001 to 2021, we apply the Feasible Generalized Least Squares (FGLS) method to examine the relationship between China’s food imports and agricultural carbon emissions of trading partners. The results indicate that the relationship supports the Environmental Kuznets Curve (EKC) hypothesis, exhibiting an inverted U–shape. This means that as food trade openness increases, trading partners’ ecological environment first deteriorates and then improves after crossing a turning point. We also find that the EKC shape exhibits national and product heterogeneity. The EKC is inverted U–shaped for high–income countries and U–shaped for low–income countries. It is inverted U–shaped for soybean imports and U–shaped for corn imports. Based on 2021 data, expanding China’s soybean imports from the United States, Brazil, and increasing corn imports from Brazil, Uruguay, Russia, the United States, and Myanmar are beneficial for improving the ecological environment of these countries. Furthermore, we discover that food trade impacts trading partners’ ecological environment through production scale, industrial structure, and technological progress, with production scale being the main path for the inverted U–shaped curve. Increasing trade openness has a positive U–shaped impact on the environment through technological and structural effects, but not enough to offset the negative scale effects. Our study contributes by confirming the EKC relationship and turning point between food trade and ecological environment, clarifying its national and product heterogeneity, and identifying the main impact channels. The findings have policy implications for optimizing China’s food import structure and promoting sustainable trade and development.

Horticulture commercialization and gender-based decision-making are valuable contributors to smallholder farmers' income. Many existing studies measure horticulture commercialization and gender-based decision-making using average treatment effects, while only a few examine heterogeneous effects. Investigating distributional effects can offer policy implications for targeted interventions to improve smallholder farmers' income. This study uses quantile regression to assess the heterogeneous effects of horticulture commercialization and gender-based decision-making on income in the Jimma zone using a quasi-experimental design sampling method with location-specific data. This study applies propensity score matching at two levels before quantile regression estimation. First, nearest-neighbor matching is conducted based on key agricultural characteristics to identify control groups at the village (kebele) level. Second, kernel matching is employed at the household level to address selection bias. Then, a total of 610 farmers were randomly sampled; among these, the treated group included farmers who were participants in the Smallholder Horticulture Empowerment and Promotion (SHEP) project between December 2022 and February 2023. The interaction effects between horticulture commercialization and SHEP intervention demonstrate positive heterogeneous effects on horticulture income, notably more pronounced at equal to or lower than 50^th quantiles. Results revealed joint decision-making significantly improves farmers' income at the 10^th and 25^th quantiles; however, the intervention did not provide an added effect to joint decision-making on income, indicating the effects of the SHEP intervention on joint decision-making could take longer to observe, as the gender training primarily focuses on behavior and mindset changes, which require a longer time to be fully internalized. Family labor, livestock holding, and proximity to agricultural cooperatives significantly correlate with income and support those in the lower quantile of income from horticulture production. Thus, for the lower-quantile farmers to benefit from the project, an effective market-driven extension approach such as SHEP is crucial to improve smallholder farmers’ income through horticulture production. More attention is needed to promote and strengthen agricultural cooperatives regarding facilities and capacity building to enhance the effective access of essential inputs to farmers especially for low quantile farmers. Moreover, this methodological innovation could be a valuable reference for future quasi-experimental and impact evaluation studies employing similar approaches in different contexts.

The deterioration of marine ecosystems due to intensified human activities has led to a significant decline in the availability of marine food sources. In response, some regions have implemented measures such as adding fertilizers to marine environments to promote the growth of seafood like clams. This study explores consumers’ willingness to purchase seafood produced using Bio–Concentrated Liquid Fertilizer (Bio–CLF), a new eco-friendly fertilizer. An internet survey was conducted in Japan with 1,546 respondents, and the data was analyzed using logistic regression and LASSO regression to examine the influence of environmental awareness, knowledge of environmental solutions, and resistance to environmental innovations on purchase intention. The results indicate that consumers with higher environmental awareness and better understanding of environmental solutions are more inclined to purchase Bio–CLF cultured seafood. These findings suggest that effective communication and education about the benefits and scientific basis of such innovations are crucial. Recommendations for seafood marketers and government agencies are provided to promote sustainable seafood production and enhance organic waste recycling.

Food contamination enhances consumer risk perceptions of food, erodes consumer trust in government food information, and alters actual consumer purchasing behavior. Imported cold chain seafood has been contaminated by novel coronavirus. However, not enough attention has been paid to economic studies of consumers purchasing imported cold–chain seafood contaminated with novel coronavirus. Given consumers’ lack of trust in government information and the coexistence of food safety risk perceptions and their own risk preferences, we aimed to explore how Chinese consumers’ trust in government information, consumers’ perception of the food safety risk and their risk preferences affected consumers’ actual purchasing behavior. This study is to examine the combined effects of consumers’ trust in government information, risk perception, and risk preferences on actual purchasing behavior. In this study, 898 consumer questionnaires were collected online after an incident of contamination of imported cold–chain seafood, and a binary logit and OLS regression was used to estimate the relationship between trust in government information, risk perception, risk preference and actual purchasing behavior. The empirical results demonstrate that the interaction term between risk perception and risk preference positively affects actual behavior. Overall, trust in the government’s information does not directly affect consumers’ actual purchasing behavior. Interestingly, subgroup regressions reveal city heterogeneity in the effect of trust in government information on purchasing behavior.

Based on the unique geographical advantage, Yantai Sweet Cherry Industry (YSCI) has been developed rapidly in past ten years. China became the top destination for worldwide cherry export, as well as Yantai has the strongest ability for domestic sweet cherry production. However, it still faces with challenges such as: labor outmigration, small–scale farmers show little interest in technology adoption, and production capital shortage. From the value chain perspective, this paper analyzes how YSCI rise influences on regional development, and how to deal with mentioned problems under dual action between technological embeddedness and organizational innovation. The results show that (1) relying on the pathway “exploit location advantage – embed key technologies – optimize value chain”, YSCI becomes the local pillar agroindustry and offers regional development. (2) Coupling technological embeddedness and organizational innovation improves economic efficiency of new agricultural management subjects. (3) Adopting key technology copes with labor outmigration stress, furthermore, taking part in advanced organization actives small–scale farmers’ interest on technology and supplies the capital gap. (4) Co–innovation of technology and organization not only reduces transaction cost, but also captures extra profit, and provides new motivation for emerging agroindustry development. During this new stage, agricultural development is supposed to pay more attention on integrated co–innovation of value chain.

Small pig holders in Vietnam face obstacles when feed costs increase daily. Therefore, identifying a cost-effective feeding mode can help farmers cope with this problem. This study compared the effects of two popular feeding modes, commercial feed and combination feed (mixing instant feed with agricultural byproducts), on the technical efficiency (TE) of small pig holders in Vietnam. The data envelopment analysis approach and meta-frontier were used to measure and compare the TE of commercial and combination feeds. Additionally, this study used a Tobit regression to analyze the factors affecting TE. TE was 75.06, 86.56, and 78.76% with the meta-frontier, commercial, and combination feeding group frontiers, respectively. The corresponding meta-technology ratios of these groups were 83.89 and 97.24%, respectively, indicating that the TE of the combined feeding mode is higher than that of the commercial feeding mode. This finding confirms the economics of combination feed in the context of increasing the import price of raw materials for feed production. The results of the Tobit models show that the education of household heads, access to credit, pig density, family income, herd size, and percentage of own-produced piglets are determinants of TE.

LCA is an effective analysis method for visualizing the greenhouse gas emissions of products and services provided by businesses in a society aiming for decarbonization, and for discovering issues that are often overlooked when assuming their social implementation. In the case of Oki Town’s human waste and food waste treatment bio gasification is viewed from the perspective of energy balance, the bio gasification was negative. However, LCA showed that the biogas plant process emitted one-tenth as much GHG as the incineration process, which was less GHG. In addition, the economic evaluation showed that the biogas plant process halved the cost of the biogas plant process. The scope of evaluation used in the economic evaluation was the same as in the LCA. In this study, the biogas plant was superior in both the greenhouse gas assessment and the economic evaluation.

This study examines the short- and long-term impacts of overinvestments on the profitability of Chinese agri-food processing firms. We construct an overinvestment age variable measured as the number of years since the most recent overinvestment and use a two-way fixed effects model based on firm-level data for the Chinese agri-food-processing industry from 1998 to 2013 to conduct the research. We find that the profitability of firms improves during the first and second years following the most recent overinvestment. However, from the third year onward, profitability declines, and the restraining effect increases year by year. In addition, we find that regional differences and differences in financing constraints can explain the heterogeneity of the overinvestment age affecting firm profitability.

“Lucid Waters and Lush Mountains Are Invaluable Assets” Policy (hereinafter referred to as “Two Mountains” Bases Policy) is put forward to address the question of how green economic development can be achieved. China implemented the “Two Mountains” Bases Policy in 2016 trying to establish bases verified and evaluated for pilot projects in which way Bases get policy support and government funds from the Ministry of Ecology and Environment of the People’s Republic of China. This study empirically analyzed the impact of Bases on green economic development using propensity score matching – differences in different methods and panel data from 2010 – 2019 concluding 2510 areas from the whole country. The benchmark regression results show that Bases enhanced both ecological protection and economic development which remains true after a series of robustness tests. The mechanism analysis results show that the government’s ecological compensation, the level of economic development, and industrial structure promote the development of “Two Mountains”. Heterogeneity analysis shows that the effect of Bases varies with different geographical locations, ocean locations, and the types of development of “Two Mountains”. Bases in the East area and Coastal area work well as well as Bases in the “Lucid Waters and Lush Mountains” leading type area. This study focuses the empirical research on the Bases at the county level, enriches the relevant literature on the practice of the “Two Mountains” Bases Policy, and provides theoretical support and policy enlightenment for the practical significance of promoting the construction of ecological civilization of socialism with Chinese characteristics.

Pork is the most consumed meat in the world and is dominantly produced in Asian countries. Numerous studies analyze pig production efficiency under alternative farm sizes which are classified by the number of pigs. While this classification does not reveal the development of farming systems, this study develops a new typology for pig farming systems: industrial farms (IFs) and traditional farms (TFs). This study describes the specific characteristics of these systems, analyzes their technical efficiency (TE), and investigates the TE’s determinants. By surveying 246 pig farms in Vietnam, we found that housing systems, feeding modes, and contract farming are the key points to distinguish IFs from TFs. Results of data envelopment analysis show that TEs of IFs and TFs are 73.8% and 65.7%, respectively, meaning that their input costs of them could reduce by 26.2% and 34.3%, accordingly, without any decreases in the outputs. In addition, analysis of scale efficiency indicates that IFs operate nearer their optimal scales than TFs do. This finding suggests the potential for TFs to increase their TE by adjusting their production scale in the long run. For short–run solutions, using Tobit models, we analyze the TE’s determinants under variable return to scale within each farming system. Various determinants were investigated, of which land rent and ratio of the manure treatment area to pigpen area substantially reduce TE of IFs, while farm–prepared feed significantly increases TE of TFs. These findings imply the need to research less–occupying manure treatment plants for IFs and lower feed prices for TFs through promoting domestic feed production and self–made feed that utilizes food waste and agricultural by–products.

In recent years, in the context of increasing environmental concerns in Japan, a growing number of consumers are more likely to purchase environmentally friendly agricultural products and foods, which gives a positive meaning for farmers to use environmentally friendly technology for agricultural production, such as using environmentally friendly fertilizers. A bio–concentrated liquid fertilizer (Bio–CLF), an innovative and environmentally friendly fertilizer derived from the current methane fermentation digested liquid fertilizers, was developed. However, producers’ evaluation of Bio–CLF, especially the intention of farmers to use Bio–CLF, has not yet been clarified. To fill this gap, a logistic regression analysis was used in this study to analyze farmers’ use intention toward Bio–CLF. The data were collected through an Internet survey administered in Japan by a market research company, and the final sample size was determined to be 263. The results indicated that farmers who had experience in using methane fermentation digested liquid fertilizer, and farmers with more knowledge of SDGs, were found to have a high intention to use Bio–CLF. Additionally, when compared with other management style farmers, outdoor vegetable farmers were found to be more likely to use Bio–CLF. Based on these results, we propose sales strategies for future Bio–CLF sales development.

This study aims to estimate the factors affecting consumers’ willingness to pay (WTP) plastic bag fees that make them agree to carry their own bags during shopping in Vietnam. Structural Equation Modelling (SEM) was applied to determine the meaningful relationship between WTP and Attitude (AT), Subjective norms (SN), Perceived behavior (PB), and Eco–Literature (EL). The survey was conducted online using a structured questionnaire through nationwide social media distribution. The main findings indicate that three latent variables AT, SN, and PB have insignificant effects on WTP. Only EL had a significant relationship with WTP. More precisely, in this relationship, the responses of environmentally aware women were stronger than those of men who agreed to bring their bags. Additionally, the fee that could affect consumers’ behavior toward reducing plastic bags was found to be at least 850.5 dong/bag (≈ 0.04 USD). This research contributes valuable evidence for the policymakers to complete Directive No. 33 which would issue a fee for plastic bags in the future. Besides, the research also provides better knowledge of consumers for using shopping bags.

This study contributes to establishing the payment function of fee-based homes for the elderly. Disclosure statements from such homes for the elderly in selected urban and suburban cities in Fukuoka Prefecture, Japan—considered a typical prefecture with adjoining urban and suburban areas—were examined. The study compared the determinants of the amounts charged by the homes based on the distinct geographic features of urban and suburban areas. The hedonic price model was combined with a two-stage least squares regression to determine the determinants of lump-sum and monthly payments. We found that the factors that influence monthly payments in urban areas include distance to a park, distance to the coast, meals offered, number of care staff, and initial lump-sum payment. In contrast, factors such as room size, distance to a bus stop, distance to a park, and the number of night staff influence monthly payments in suburban areas. We conclude that the surrounding landscape has a greater influence on monthly payments in urban areas than in suburban areas. Moreover, in suburban areas, the number of night staff has a substantial impact on monthly payments. The results can help provide investment suggestions in certain cases depending on the amount of investment capital.

Recently in Japan, under the context of increasing environmental concern, an increasing number of consumers are more likely to purchase green products. Bio–concentrated liquid fertilizer (Bio–CLF), an innovation derived from current methane fermentation liquid fertilizers, will help to produce a new kind of green product in the future. This study used conditional logistic regression to analyze Tokyo, Osaka and Fukuoka consumers’ preferences for Bio–CLF rice. The results showed that when compared with ordinary organic fertilizer, although the rice cultivated by Bio–CLF (food waste, sake brewing waste, and milk waste) suffered a negative reputation among consumers, the marginal willingness to pay (MWTP) of the Bio–CLF rice is still higher than that of most chemical fertilizer–cultivated rice. Additionally, when considering consumers’ income, knowledge of organic fertilizer raw materials, and green product purchase intention, the MWTP of the Bio–CLF rice will be much higher. This study will contribute to providing basic analysis data of Bio–CLF and help to popularize Bio–CLF, increase the utilization rate of methane fermentation digested liquid fertilizer, and eventually improve the environment.

The fishing ban policy in the Yangtze River Basin is an important measure to implement the concept of prioritizing ecological conservation and boosting green development. The resulting problem in the livelihood of retired fishermen has become a new challenge to consolidate the achievements of poverty alleviation and to construct an overall well–off society. Based on the sustainable livelihood approach framework, this study constructs the livelihood capital evaluation index system of Ma’anshan City’s retired fishing households, calculates their sustainable livelihood capital index, and identifies the effect factors of livelihood strategy choice and transformation of fishing households. The results show that: In the four types of household livelihood strategies, the Short Term Employment household has the lowest livelihood capital index and the Self Employment type has the highest. Human capital has a significant negative effect on the choice of Short Term Employment and Single Long Term Employment strategies, and a significant positiveeffect on the households’ choice of Couple Long Term employment and Self Employment strategies; Financial capital has a significant positive effect on the choice of Self Employment strategy of households. Education level, professional skills, annual household income, residential area and loans are the key factors for the strategy transformation from Short Term Employment strategy to others. Strengthening the construction of human capital, promoting the development of financial capital and scientifically planning the industrial structure of the fishing ban area are effective measures to protect the livelihood of retired fishing households and promote the households’ strategy transformation to high level of livelihood strategies.

In this study, we conducted a hypothetical choice experiment in Beijing, China, to investigate residents’ preferences for selected household kitchen waste source separation service attributes. A latent class approach was applied to observe heterogeneities among the respondents. The econometric analysis suggested that two classes of residents exist in the sample. Interestingly, 70.1% of the sample who were high educated, young, and with separation experience are more likely to accept the proposed separation services with frequent evening collection, while they do not show significant preferences for the attributes of instructor, container, and compensation. For the remaining (29.9% of the sample) who were low educated, old, and with less separation experience, joining the separation program would impose a loss of utility. Moreover, they seem to prefer services with the attributes of frequent collection, plastic bags, and compensation. However, they do not show significant preferences for the attributes of time and instructor.

Although there are many studies on evaluating ecosystem services in recent years, most of the studies focus on the externality of ecosystem services. Fundamentally, it is important to understand market internalized value of ecosystem services, but studies on this point of view are rare as far as the author knows.
This study evaluates the impacts on the local economy, as an internalized value of ecosystem services, caused by shifting from conventional to bio-friendly rice farming, using a case study of stork-friendly rice farming (to help conserve white storks) in Toyooka, Japan. After applying an input-output analysis, we consider whether stork-friendly rice farming created a net positive economic impact on the local economy.
The results shows that changing from conventional to stork-friendly rice faming had a high induced effect and that shifting to stork-friendly rice faming creates a net positive economic impact on the local economy.

Three different sizes of hog farms were selected to analyze the carbon emissions reduction and the costbenefit of three methane digester systems. The sizes of the digesters are 2,200, 2,200 and 800 m3, respectively. The sales of slaughter hogs from them are 50,000, 35,000 and 10,000 head, espectively. The carbon emissions reductions were 5,237, 4,017, and 1,334 tons, respectively. The results show that while the methane digester systems have a significant effect on carbon emissions reduction, it is difficult to operate the systems sustainably. If the carbon emissions reduction can be traded at high enough prices in the carbon offset markets, then the systems will be profitable and sustainable. Newly established China’s domestic carbon offset market could provide this possibility, but more government support is needed. In addition, this study shows that scale economies make he digester adoption relatively more profitable for larger farms than smaller ones.

China’s “Agricultural Leading Enterprise Program” (ALEP) could promote the total factor productivity at micro level. Actually, there are many disputes about selective industrial policies at present. Using China Industrial Enterprise Database, this study selects the ALEP as
an economic experiment to research whether selective industrial policy is effective. The conclusion is positive after using Propensity Score Matching-Differences in Differences (PSM-DID) to control endogeneity problem. Specifically, the ALEP’s average promotion effect is 4.66%, and the policy could remain effective in the long run. This study further finds that state-owned enterprises could obtain better policy effects compared with non-state-owned enterprises. The ALEP achieves results in tax incentives but could not reduce the financing
constraints faced by enterprises, which means there is still a lot of room for the government to execute the program’s financial assistance.
