Abstract
First introduce the efficiency evaluation model; secondly, establish an industrial technology innovation efficiency evaluation index system consisting of 4 input indicators and 4 output indicators; Then use the canonical correlation coefficient method to determine the lag period, use the GDP deflator to eliminate the impact of price changes, use the mean method to perform the dimensionless processing of the indicators, and use the factor analysis method to determine the weights of the indicators; finally, use the efficiency evaluation model to comprehensively measure and analyze the efficiency of industrial technology innovation in Hebei Province from 2009 to 2018, and point out the characteristics of its development. The results show that the efficiency of industrial technological innovation in Hebei Province fluctuates greatly, but the overall trend is increasing; the efficiency of technological innovation in Hebei's industry is closely related to the policy environment.
