Abstract:Based on Porter"s diamond theory model, this thesis constructs the index system for the analysis of competitiveness of sci-tech business incubators and makes a quantitative analysis of the relationship between the factors and competitiveness of China"s sci-tech business incubators. The results show that the number of R D personnel in the country, the proportion of R D in GDP, the intensity of venture capital investment, the Internet penetration rate, the number of employees in the incubation business, the per capita GDP, the number of productivity promotion centers, and the proportion of public expenditure have positive influence on science and technology business incubator competitiveness. The domestic application patent authorized number, incubator area, in hatch enterprise number, and social financing scale stock, high-tech enterprise export earned, and enterprise income tax are negatively correlated with the competitiveness of China"s science and technology business incubator. According to the research results, this paper puts forward some suggestions for the promotion of competitiveness of China"s sci-tech business incubators.
