Research On Spatial Measurement Of Technology Innovation Promoted By Science And Technology Finance

In recent years,as one of the high and new technology industry area in China,the pearl river delta region has a rapidly developing economy with lots of policy support,its science and technology innovation industry flourishes as well.Therefore,studying the characteristics of technological innovation and development in the Pearl River Delta is conducive to optimizing the system of technological finance-technological innovation,and is also of great reference significance for technological innovation and development in other regions.Based on the spatial interaction of 9 cities in the Pearl River Delta,this paper studies the output of technological innovation from the perspective of investment in science and technology finance.In terms of science and technology finance,this paper selects the fiscal appropriations of science and technology,enterprise R&D spending,bank borrowing of science and technology company,financial institutions,loan balance,total market value of listed company of science and technology,science and technology risk capital market financing and venture investment as the representative indicators.In terms of technology innovation,starting from the development stage,it selects the amount of patent authorization,the amount of technology contract transaction,and the output value of high-tech products for reference.Two comprehensive indexes were calculated by entropy weight method to analyze the development status and existing problems of science and technology finance and technology innovation in various cities,and the relationship between the influence of each index of technology innovation and science and technology finance investment was analyzed by establishing the space dubin model with two fixed time and space.This paper finds that the technological innovation level of cities in the pearl river delta is not only influenced by the technological and financial input of cities,but also by the technological innovation level and technological and financial input of neighboring cities.Among them,the enterprise R&D expenditure has the significant opposite influence to this city and the neighboring city,has the certain promotion effect to the former,the latter is weakens the effect;Loans from financial institutionshave the same influence on this city and neighboring cities;The amount of financing,venture capital and financial investment in science and technology also have slight promotion and adverse effects on the city and neighboring cities respectively,that is,leading to the competition effect between the city and neighboring cities.According to the research conclusion,the paper suggests that the government should take different support measures according to the development level of the cities,and pay more attention to guidance and training for the backward cities.Market and venture capital should cooperate to promote the connection of resources between supply and demand;Enterprises and individuals should attach importance to technological innovation and correct the attitude of scientific research.In a word,the cooperation of science and technology financial entities is the driving force for technological innovation to make breakthroughs.
