Tax incentive and technology innovation —The empirical research based on the listed companies

From the view of tax categories and incentive modes, employing the published information of 87 listed companies from electronic information, software, machinery manufacturing and measuring instrument in Shanghai and Shenzhen stock markets, this paper analyzes the effect of existing tax incentive policy on the enterprises´ technology innovation in our country. The results show that our existing tax incentive policy composed mainly of income tax, has a positive incentive effect, and compared with income tax preference and direct incentive mode of tax rate, circulation tax preference and indirect modes of tax basis and tax amount are more incentive. This shows that the current tax policy needs further adjustments. The basic direction is to strengthen income tax incentives, and to set up an integrated and coordinated relationship between incentive tax categories (income tax incentive and circulation tax incentive) and among incentive modes (tax base incentive, tax amount incentive and tax rate incentive) according to the different characteristics of taxes and incentive modes, and to construct a tax incentive policy system which provides enterprises full support to undertake technological innovation from beginning to the end.
