Innovation is an inexhaustible driving force for national development, and patents are a favorable tool for a nation to obtain and maintain competitiveness. In order to make patents a strong competitive advantage, it is necessary to actively promote the development of scientific and technological innovation activities. Based on the statistical analysis of the longitudinal data onto nine cities in Zhejiang Province in each decade, we explore the main factors affecting the number of patent applications. Through correlation analysis and stepwise regression, variables are screened to establish a linear regression model, and the random effect is added to the regression coefficient. The regression results show that there are obvious differences in patent levels among cities. The relative size of the influence factors on the number of patent applications are local fiscal expenditure > main business income of industrial enterprises above scale > foreign investment > total import and export goods.
