摘要：Poor development in financial markets may hinder firms from achieving environmental regulation goals set by governments. By using a policy change of environmental regulation in China and exploiting cross-city variation in banking concentration, we study how competition in local banking market affects the effectiveness of environmental regulation. Results indicate that banking industry competition played a positive role in assisting firms' reduction in SO2 emission to meet environmental regulation targets. Firms located in cities where banking competition is fierce tend to invest more in desulphurizing capacities when faced with a tightening of regulation. Both long-term debt and current liability increased for firms in cities with tougher banking competition, suggesting these processes may be facilitated by bank financing. These results are indicative that a well-functioning banking sector plays a critical role for environmental regulation to be effective.
题目二：Does migration experience reduce villagers’ social capital? Evidence from rural China
摘要：In this study, we examine the impact of migration experience on return migrant’s social capital using household survey data from rural China. We first develop a simple model to describe rural household’s decision to invest in social capital and then empirically examine how migration experience affects social capital using village-level natural disasters as instrumental variables for migration experience. Our results show that villagers’ migration experience reduces both structural social capital and cognitive social capital. Compared with those who never worked out of their own hometowns, return migrants would practice fewer social interactions, information communication, trust building and reciprocal behaviors with relatives. We provide suggestive evidence that the decline in social capital may be caused by the higher expected mobility of return migrants.
题目四：Consumers’ Acceptance and Valuation for Cultured Meat: A Multi-city Choice Experiment in China
摘要：Cultured meat is an unfamiliar emerging food technology that could provide a near endless supply of high quality protein with a relatively small ecological footprint. However, the successful adoption of a novel food technology not only depends on its technical feasibility, but also consumers acceptance and demand for the novel food product. To understand consumer acceptance and valuation of cultured meat, the study examines the impact of positive and negative information on consumer willingness-to- pay (WTP) for cultured chicken breast. A random sample of 1139 Chinese consumers from Beijing, Shanghai and Guangzhou completed a survey instrument that included four information treatments and a choice experiment. Empirical results showed that consumers have a negative WTP for cultured meat, about ￥-10.22/500g,while information induced the increase of consumer WTP. In which a combination of positive information and negative information about cultured meat have the largest effects on the increase of WTP for cultured meat, followed by negative information, and the last is the positive information. More comprehensive information in a relevant context could therefore contribute to the commercial success of cultured meat.
