自2013年十八届三中全会决议正式提出“发展普惠金融”以来,我国的小微金融得到快速发展,小微企业银行信贷可及性明显提高,贷款成本显著降低。但是,目前的普惠金融政策并没有覆盖到中型企业,中型企业的融资难融资贵问题反而开始突出。... 自2013年十八届三中全会决议正式提出“发展普惠金融”以来,我国的小微金融得到快速发展,小微企业银行信贷可及性明显提高,贷款成本显著降低。但是,目前的普惠金融政策并没有覆盖到中型企业,中型企业的融资难融资贵问题反而开始突出。本文选用邮储银行的贷款微观数据,分析了普惠金融政策的实施效果,发现普惠金融政策能有效使受惠企业利率下降,贷款余额增加,信用贷比例上升。进一步,本文利用反事实的方法关注了将普惠金融政策扩面到中型企业后对其融资能力的影响,发现普惠金融的扩面能有效缓解中型企业的融资困境。本文强调应该认识到融资政策的结构性问题,加大对中型企业的支持力度。 展开更多

With rapid urbanization,millions of rural villagers have become urban citizens in China.This paper estimates the effect of the in situ urbanization policy on an individual's health by employing the difference-in-differences framework and using panel survey data from the China Family Panel Studies.Our findings show that this program,unlike other kinds of urbanization,which have had negative impacts on mental health or made people smoke or drink more,increased people's self-reported health status significantly.Further mechanism analysis reveals that the in situ urbanization policy afected health by increasing people's confidence in the future,their satisfaction with their current lives,and their medical insurance enrollment.This study highlights the importance of"the city comes to villagers"urbanization in China,and it can play an essential role in advancing the urbanization rate and avoiding the negative impacts of urbanization on health. 展开更多

This paper examines the motivations of parent-child co-residence behavior in China using data from the China Health and Retirement Longitudinal Study.We test three possible motives:social norms,self-interest and altruism.We find that social norms play an important role in household co-residence behavior,showing that the belief that"sons take care of parents"is strong,and children in different birth orders take different responsibilities.Taking the one-child policy as a natural experiment,we compared co-residence behavior between only-child and multi-child families.This allowed us to test whether children in multi-child families with wealthier parents more often coreside in order to compete for a bequest.We find that parents'wealth is more appealing to children in multi-child families.The results support the life cycle theory that coresidence decisions are motivated by self-interest.We also find some evidence of altruism when parents and children make co-residence decisions.These findings provide some insights for designing future elder-support policies in China. 展开更多

The unemployment rate is a key indicator of labor market and economic performance. Based on a unique survey, we estimate the unemployment rate at 13.44percent in 30 provincial capital cities in China in 2007, which is well above the officially announced registered unemployment rate. The discrepancy results from inaccuracy in the calculation of registered unemployment. The discrepancy is not stably evolving across regions or over the years, making it difficult to recover the true unemployment rate using a simple multiplier approach. We further investigate the sources of the discrepancy by examining the determinants of unemployment registration. It is evident that participation in certain public activities, which would facilitate the spread of knowledge related to job-searching and unemployment registration, encouraged unemployment registration. Social attention to government antiunemployment programs also encouraged unemployment registration. These findings confirm the behavioral hypothesis that incomplete knowledge and limited attention can cause deviation from optimal choice. The policy implications of the findings of the study are discussed. 展开更多

In this paper, we emphasize the interactive effect between life expectancy and human capital accumulation, and test the positive feedback of longevity to educational investment in China. This is very important for understanding the pressure from the aging population and the increase in private educational investment in China. We first show in an extended human eapital investment model that life expectancy growth acts as a driving force for educational investment. We then build a difference-in-difference-in-differences empirieal framework and use cross-province data to examine the effect in China. We use the maternal mortality rate (MMR) to identify the difference in life expectancy between genders, and the illiteracy rate or average years of education by gender for educational investment. The empirical results comply with the theory, in that increases in life expectancy significantly lower illiteracy rates and improve the average schooling years in China. This content of the present paper is closely related to crucial issues like population aging, human capital accumulation and gender discrimination. Policy implications are discussed based on the empirical results. 展开更多
