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.
题目四：The Effectiveness of Anti-Poverty Programs in China: Evidence from CHIP dataset from 1988 to 2008
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.
