Can the supportive policy for resource-exhausted cities promote industrial enterprises to reduce emissions?
Based on the data of industrial enterprises'pollution emission in China from 2004 to 2012,and taking SO2 emission as an example,this paper discusses the influence and mechanism of supporting policies for resource-exhausted cities on industrial enterprises'pollution reduction by using multi-period double difference method.The research shows that the supportive policy for resource-exhausted cities can significantly reduce SO2 emissions by promoting enterprises to strengthen source prevention and end treatment,especially improving the treatment capacity of waste gas treatment facilities.The results are supported by parallel trend test,a series of placebo test and robustness test.Although the policy failed to make enterprises change their energy use structure,it did not force enterprises to reduce production at the expense of the economy,either.Further analysis shows that the policy has a heterogeneous impact on enterprises in different positions in the industrial chain,and downstream enterprises have achieved greater emission reduction effects,which has planted a green background for industrial upgrading in the city.
