||Kana Moroga, Yutaka Ito, Shunsuke Managi, Toshiyuki Fujita, The Effects of CO2 and NOx Emissions Reduction and Power Generation Mix on Next Generation Vehicles Diffusion in China, 環境経済・政策学会2012年大会, 2012.09, In this paper, we use a cost-benefit analysis to evaluate the diffusion prospects of hybrid vehicles (HVs) and electric vehicles (EVs) in China. We set up some scenarios accompanying the purchase and replacement of gasoline-fueled vehicles with HVs and EVs, and conduct an analysis of the energy consumption by vehicles or the effects of CO2 and NOX emissions reduction. We also extend the analysis taking into consideration the CO2 emissions reduction of power generation for EVs diffusion. This research examines the effects of vehicle’s emissions control and gasoline use reduction, and the impact of the power generation by analyzing the effects of various factors’ change on the value of the benefit-cost (B/C) ratio to verify the validity of next generation vehicles diffusion from a social and economic perspective. Our results suggest that it is beneficial to promote the diffusion of HVs which has empirically higher returns in China..
||Kana Moroga, Toshiyuki Fujita, Environmental-Energy Policies and Technology Transfer for the Chinese Automotive Industry, The 5th International Symposium on Environmental Economy and Technology, 2012.08, We build a theoretical model as Bertrand competition and examine through numerical simulations the situation in which to promote either hybrid vehicles (or gasoline engine vehicles) or electric vehicles taking into account the influence of investment ratio regulation by joint venture. We investigate the effects of investment and subsidy which are considered as environmental policies and clarify the effects of investment ratio regulation on the joint-venture firm. Our results show that, when the environmental damage is large, decision-making of the Chinese government does not lead to a maximization of the social welfare. Besides, given the high cost and damage associated with electric vehicles, the effects of subsidy on hybrid vehicles increase the social welfare the most. Therefore, it is better to follow a policy promoting an efficient use of hybrid vehicles..
