Abstract: As a policy arrangement to motivate enterprises to innovate in green technologies and to comprehensively use resources for pollution reduction, the preferential tax policy for recycling resources has been implemented for many years. The existing policy evaluation researches have considerable flaws in their methods and data resources. This paper uses PSM method to conduct an empirical test of the micro enterprises data from the national tax survey. The findings show that this policy has a significant reduction effect on manufacturing enterprises’ full use of the intermediate products and the waste; as for the professional waste resources comprehensive utilization enterprises (the environmental protection enterprises), the preferential policies have increased the amount of waste purchased by such enterprises by 15%~17%, that is, the policy has promoted the formation of a professional waste disposal market. However, the policy does not inspire green technological innovation in the manufacturing industry. In order to enjoy the preferential policies, a number of enterprises have adopted low-end physical methods to deal with the waste, and the products have the risk of secondary pollution. Therefore, it is suggested that the identification conditions for the preferential policies should have a higher threshold and the enterprises should be encouraged to develop and apply high-end environmental protection technologies, so as to truly improve the level of green technology innovation of the enterprises.
