Research on the Impact of Financial Agglomeration Based on Big Data Analysis on the Technological Innovation Efficiency of SMEs

If technology and finance can be effectively connected, they can better promote the transformation of technological innovation achievements, improve production efficiency, realize the transformation of technological innovation achievements into economic benefits, and indicate the direction for China's economic development. This article analyzes the rapid flow and efficient allocation of financial elements and resources at the spatial level through big data, and the results show that government subsidies and tax incentives have a promoting effect on the efficiency of technological innovation of small and medium-sized enterprises in the growth stage. For technology-based SMEs in the recession, the coefficient of influence of government subsidies on technological innovation efficiency is positive, significant at the level of 15%. Although the coefficient of influence of tax incentives on technological innovation efficiency is also positive, it is not significant. It can be seen that policy support for the listing and listing of enterprises should be strengthened, and a full process support system for the listing and listing of enterprises should be established. Listing, listing, refinancing, mergers and acquisitions should be conducted in regional equity trading markets, national small and medium-sized enterprise share transfer systems, and domestic and foreign stock exchanges, so as to effectively play the financing function of the capital market.
