THE REGIONAL DISPARITY OF INFLUENCING FACTORS OF TECHNOLOGICAL INNOVATION IN CHINA: EVIDENCE FROM HIGH-TECH INDUSTRY
利用2009-2016年中国27个省份的高技术企业数据，通过PSO-GRNN模型和敏感性分析，发现创新投入、市场环境、政府支持和国外技术溢出是影响企业技术创新的主要因素，且这些因素在东、中、西部地区存在显著差异。
Accurate analysis of technological innovation mechanism in different regions is the key to promoting China’s technological innovation, economic transformation and upgrading. This paper collected statistical data of high-tech enterprises in 27 provinces in China from 2009 to 2016, established a novel PSO-GRNN model, and applied sensitivity analysis to explore the influencing factors and regional differences of enterprise technological innovation in Eastern, Central and Western China. The empirical results showed that the influencing factors were innovation investment, market environment, government support and foreign technology spillover sorting by impact size. Innovation investment was the decisive factor of technological innovation, but innovation resources mainly concentrated on Eastern China, severely insufficient in Central and Western China. Market environment was favorable to Eastern and Central China, but unfavorable to Western China, which restricted greatly the development of Western China. The principalagent problem of state-owned enterprise and the crowding out effect of government research and development funds jointly led to the negative influence of government support on technological innovation. Foreign technology spillover had significant positive effects on technological innovation in Western China. This paper clarifies some disputes about influencing factors of technological innovation and provides a new research perspective for related issues.
