摘要：
Chinese government has recently made great effort in tackling the water pollution issue, and a series of water regulation policies were implemented to reduce water pollution from livestock production. This article discusses the costs and impacts of the water regulation. The water regulation is gradually expanded during 2010 to 2016 across regions and years, and this nature allows us to construct a staggered DID to identify the causal effects. Our estimates show that the implementation of water regulation reduces the NH-index of water pollutant by 22.3%, but by the cost of a reduction of 8.3% of livestock pig production, 10.3% reduction of livestock pig in stock, and 11.2% of pork production. However, other water pollutants (i.e. pH, DO and COD) are not significantly reduced. Further analyses show that the reduction of pig production is partially substituted by meat structural change within counties and by spatial change of livestock production, instead of relying on pig import. As a result, the effectiveness of the water regulation policy is very limited, due to 1) only specific water pollutant responded and 2) possible water pollutants transfer across regions. This study contributes to a growing body of literature on the argument regarding the tension between environmental regulation and economic development at regional level.
题目二：经济集聚对农民增收的影响研究
报告人：赵吕航博士生
摘要：
中国在农民增收方面取得了重大成就，探究如何提高农民收入具有现实意义和借鉴作用。经济的空间集聚是经济发展的重要现象，现有的研究更多的基于宏观数据考察经济集聚对农民整体的收入增长的影响，缺乏个体微观变量的引入。本文结合宏观与微观数据研究集聚经济如何影响农民收入，研究表明，经济密度对农民收入具有显著的正向直接影响，其中主要通过影响农民的非农就业实现增收。
题目三：食品安全标准对中国蔬菜出口的影响研究——以日本“肯定列表制度”为例
报告人：施展艺博士生
摘要：
随着消费者食品安全意识的提高，为保障国内食品市场安全有效运行，政府往往会为食品，尤其是进口食品制定较为严格的食品安全标准，仅允许符合标准的食品进入本国市场。特别是近年来全球范围内食品安全事件频发,发达国家食品安全标准的不断提高，食品安全标准对农产品贸易的影响正受到越来越多的关注。本文以日本“肯定列表制度”和中国对日蔬菜出口为例，通过匹配海关贸易数据和工业企业数据库的年度、月度数据，采用DID模型实证分析了“肯定列表制度”的出台对中国出口日本蔬菜的影响，并探讨了其对于不同类型企业的异质性影响。结果显示：“肯定列表制度”的实施确实对中国蔬菜和农产品出口产生了显著的负面影响，对于蔬菜的影响要大于对全体农产品的影响。不同类型的企业受到“肯定列表制度”冲击的程度不同，资产规模和工人规模更大的企业受到“肯定列表制度”的冲击更强，TFP较大的企业受到的冲击也要高于平均水平。
题目四：The Effectiveness of Anti-Poverty Programs in China: Evidence from CHIP dataset from 1988 to 2008
报告人：程铭达博士生
摘要：
This paper uses CHIP dataset from 1988 to 2008 to evaluate whether two waves “National-level Poverty-Stricken County” (NPSC hereafter) can benefit individuals. We construct a difference-in-differences (DID) strategy to identify the causal effect of county-level NPSC program on individual-level outcomes. This is a plausible identification, cause though the assignment of NPSC is an endogenous and comprehensive consideration of county socio-economic factors, whether and when the county one lives in is defined as a NPSC is a plausibly exogenous shock to local residents. We find that NPSC program has a large positive casual impact on individual outcomes: significantly increases individual’s income by 36.9%, together with an additional 3.63% employment. Further analysis reveals that the increase in individual income in wave 1994 is mainly due to extra job opportunities, while the increase in individual income in wave 2001 is driven by changes in employment structure. Heterogeneous analyses show that the, poor and lower educated group benefit more than the rich, which sheds light on the extensive margin and intensive margin. Potential mechanisms through which the NPSC programs eventually benefit individuals are found to be basic education and government investment.
