Does Porter Hypothesis Exist? - Take Major-Surveyed Industries in Jiangxi Province as an Example

With 2001-2008 panel data of major-surveyed industries in Jiangxi, we do the empirical test on industrial competitiveness, innovation capacity and environment protection capability of environmental policy regulation, to test Porter hypothesis. We find Pollution tax policy has the best performance, emission abatement investment policy be the second. While the "three simultaneous" implementation policy, administrative punishment policy and the policy of public partition do not play their roles because of the execution and coverage. Among them, the pollution emission tax policy elasticity on technology innovation and profit-cost ratio are 0.97 and 0.007; the elasticity on wastewater, waste gas, SO2 emission intensity are -1.47, -1.21, -1.37 respectively. All the conclusion is agree to Porter Hypothesis, so it is helpful to implement environment policy under low-carbon economy.
