Research On The Effect Of Government R&D Funding Based On Threshold Regression Model

Nowadays,science and technology innovation ability is not only a key point of the development of the country,but also a necessary condition for the development of the national economy.If a country wants to keep itself at the forefront of the tech industry,it needs to rely on its own technological innovation ability.In recent years,our country has paid more and more attention to the scientific and technological innovation,and put the scientific and technological innovation in the core of the development.However,due to the risk of technological innovation and technology spillovers,it requires the government to guide enterprises to innovate,thereby stimulating the market's innovative vitality.From the results of previous studies,the impact of Government R&D funding on enterprise innovation can be divided into three types:incentive effect,crowding out effect and inverted U type.This paper firstly analyzed the present situation of high-tech industry R&D activities to understand the level of R&D investment in china,and used DEA method to measure the input and output efficiency of high-tech industry R&D activities.It mainly measured two R&D Efficiency:one was not considering the efficiency of government funded R&D,and the other was considered the efficiency of government funded R&D.By comparison,it was found that government funding was helpful to improve R&D efficiency.Then,it used the threshold model to calculate the optimal government funding scope of high-tech industry.The results showed that when government funding as thethreshold variable,Three industries all passed the double threshold model test,The coefficient of the labor and the capital were positive number.However,due to the heterogeneity of the industry,The threshold value of the three were different,The government should choose the best scope of funding to stimulate innovation.Then used the threshold model to measured the effect of control variable on government funding.There were big differences between these three factors on the government subsidy.Therefore,the government should be based on the industry,the level of economic development in the region,the size of the enterprise and the actual rate of profit to finance,so as to maximize the effectiveness of funding.
