Abstract：
On the base of establishing financial development index and its structural indices, this paper empirically tests the impacts of financial development on releasing the financial constraints of hi-tech enterprises and their R&D investment efficiency. The result shows that financial constraints exist widely in China’s hi-tech enterprises. Financial development can release the financial constraints of hi-tech enterprises, and further promote the increase of their R&D investment efficiency. But the impacts of financial intermediary development are significantly higher than that of the stock market development. In addition, the effects of financial development on state-owned hi-tech enterprises are more significant in terms of releasing financial constraints and promoting R&D investment efficiency. It concludes that it's beneficial to improve the financial environment and optimize the capital allocation by improving the policy environment of financial constraints and developing multi-level capital markets.
