Abstract:The capability of independent innovation is an accelerator for regional development. Since 2008, Anhui Province has formulated and implemented a series of preferential tax policies concerning independent innovation, and has significantly improved regional innovation capabilities. This article is based on the text of 188 innovation tax preferential policies of provincial and prefecture-level governments in Anhui Province from 2008 to 2017, from the policy year of issuance, policy issuance area, policy objects, preferential tax types, policy preferential measures, and policy text forms. Dimensions are statistically and quantitatively analyzed. While revealing the development history of the tax incentives for independent innovation in Anhui Province, five issues have also been revealed: the frequency and density of policies issued are obvious; the frequency and density of regional policies vary greatly; policy targets are for industrial industries, technological innovation, There is a significant tilt in crowd-sourced development; taxation of preferential tax policies and design of measures are unreasonable; and the lack of specific operational policies is a corresponding issue.
