Does environmental regulation slow down marine environmental pollution?--Empirical study based on panel threshold model

Abstract

In order to identify the real impact of environmental regulation on the marine environment pollution in China, the paper constructs a panel threshold model of environmental regulation on the marine environment pollution, by adopting data from year 2006-2016 of 11 coastal provinces and cities in China, perform a linear regression analysis and a threshold regression analysis, taking environmental regulation as a threshold and explanatory variable, population at the end of the year, the GOP and total population, GDP as control variables, the annual amount of wastewater discharged directly into the sea as dependent variable. The results show that environmental regulation cannot slow down marine environmental pollution, China's environmental regulation has a significant threshold effect on marine environmental pollution, GOP and GDP have significant positive impacts on marine environmental pollution, and impact of GOP is higher than that of GDP, and population has insignificant negative impacts on marine environmental pollution. Therefore, regulations should be improved to protect the marine environment.
