Ecological compensation in transboundary watersheds and economic growth in compensated counties:A quasi-natural experiment based on the third round of ecological compensation in Xin'anjiang River Basin
The transboundary watershed ecological compensation mechanism is an essential institutional innovation to promote the construction of economy and ecological civilization synergistically,and to promote the high-quality coordinated development of the region.This paper adopts the double-difference method to assess the impact of the implementation of the third round of the transboundary basin ecological compensation policy of Xin'anjiang River Basin on the economic growth of the compensated counties.The results of the study show that the third round of the transboundary basin ecological compensation policy of Xin'anjiang River Basin significantly promotes the economic growth of the compensated counties.Gross domestic product(GDP)and GDP per capita in compensated counties increased by about 4.4％and 4.3％,respectively.The three rounds of the transboundary basin ecological compensation policy that lasted nine years has obvious dynamic cumulative effects.The integrated analysis found significant differences in the impacts of the three rounds of transboundary basin ecological compensation policies on economic growth in the compensated counties of the Xin'anjiang River Basin.In addition,the robustness of the research conclusions is proved by a series of tests such as the event study method,randomly generating the experimental group,and synthetic control methods.Further,the mechanism analysis verifies that differences in the level of economic development and regional financial pressure will have a differentiated impact on county economic growth,and the opening of the Hangzhou-Huangshan high-speed railway deepens the positive effects of the transboundary watershed ecological compensation policy on the promotion of economic growth in the compensated counties.
