Abstract
Choosing institutional environment and key executives political association as basic study background. We select the data of the private listed companies in Shanghai and Shenz during 2013 and 2015 as the study sample as a new view of thought and empirically study the relationship of earnings management and key executives political association. By testing ,the results have proved the suspects. We find that the factors of Chinese enterprise R & D expenditure levels are related to the regression analysis, an empirical test of the relationship between private listed company executives political association and the institutional environment and spending on research and development. The set defined as political connection between the government and enterprises are the hidden relationship between government and enterprises, and key executives political association. The results of this study also show that the level of R & D expenditure of enterprises with political connection is lower, the better the system environment of enterprises in the province, the higher the level of R & D expenditure. The research conclusion has a certain significance to explain the reason of low level of R & D expenditure in Chinese enterprises, and it is meaningful to think about the mechanism of Chinese entrepreneur’s innovation spirit.
