Abstract: The dispersion of industrial policy describes an implementation mode of industrial policy. If the industrial policy is used for most enterprises of industry,it is considered that the industrial policy has a better industrial policy dispersion. The enhancement of industrial policy dispersion promotes the competition among enterprises and helps to improve the TFP of enterprises. Taking the data of Chinese industrial enterprises from 1998 to 2007 as the sample,this paper used panel data fixed effect model and instrumental variable method to test the influence of ownership structure on the dispersion of industrial policy from the experience level,as well as the difference of the influence of ownership structure on the dispersion of industrial policy under different marketization levels. The study finds that the increase of the proportion of state-owned capital reduces the dispersion of industrial policy through "identity effect" and "rent-seeking effect". Given the ownership structure of an industry,the market-oriented reform is helpful to reduce the negative effect of the dispersion of industrial policy caused by the proportion of state-owned capital.
