Meifen Chu Guangyuan Zhou Wenfeng Wu (2021), Data Envelopment Analysis on Relative Efficiency Assessment and Improvement: Evidence from Chinese Bank Branches(査読つき), Eurasian Studies in Business and Economics (Springer)(Accepted 2021/7/17), 2021.07, By creating credits commercial banks contribute to the national economy and their branches are the catalysts of depositing, lending and other associated activities. To comprehend the efficiency of commercial banks their branches must be brought under the microscope. The purpose of this paper is to analyze the comparative efficiency of the bank branches from a micro point of view by introducing environmental changes. Firstly, we utilize Data Envelopment Analysis (DEA) to micro-analyze 18 bank branches of a Chinese commercial bank. Secondly, we decompose the effectiveness into efficiency and productivity to estimate the bank branches’ relative efficiency and productivity. To add, we also examine overall productivity along with average efficiency that assists in understanding each staff’s performance; this is a rarely investigated territory. Thirdly, we employ operating environment factors—a novel approach—with three dimensions (business conditions, competitiveness and future development) to further detect and rank bank-branches efficiency. We found that some branches performed efficiently (inefficiently) even in lower (higher) external environments; hence, locations and individual performance are vital influencers of bank branches' efficiency. We recommend practical measures to improve the efficiency of inefficient branches in the areas of expense, revenue, and management; this will be beneficial for any commercial bank’s policy-making efforts..
2. Meifen Chu(2020), WAVELET ANALYSIS OF THE EURO AND ITS CO-MOVEMENT WITH FOUR EXCHANGE RATES(査読つき)
, EURASIAN JOURNAL OF SOCIAL SCIENCES, DOI: 10.15604/ejss.2020.08.03.004, 8(3), 2020,, 123-133, 2020.10, The objective of this study is to examine the characteristics of the Euro exchange rate and its co- movement with four main currencies (the AUD, POUND, YEN, and RMB). After the Euro was adopted as an official currency in EU area, it grew rapidly and became the second most-traded currency in the world. The increasing importance of the Euro drew much attention from researchers and policymakers. This paper employs the wavelet analysis, which has become popular and recently is applied in various fields, such as medical science, radio science and social science. First, this paper observes five currency exchange series: the EURO, AUD, POUND, YEN and RMB. Next, using wavelet analysis, it examines the characteristics of each series. Then, a wavelet coherence analysis is used to examine the interdependence between the EURO and the other four currencies. The results indicate that the Euro displays a greater interdependence with the AUD and POUND, while it has lesser correlations with the YEN and RMB. This implies the Euro co-moves with the American and European exchange markets while it is less related with the Asian counterpart. It is interesting to note that the Yen led the Euro during the global financial crisis. Further, the Euro has interdependence with the four exchange rates at shorter periodicities during the crisis periods and is correlated with the four at long periodicities in the long run..
