Abstract: Promoting the technological innovation of enterprises is the key to realize the innovation-driven development in China. By creating and stimulating market demand, government procurement can have an important impact on the technological innovation of enterprises. Meanwhile, when analyzing the innovation performance of government procurement, the analysis of industry differences is of vital importance. By using the enterprise survey data from the World Bank and classifies the industry types scientifically, this paper empirically examines the impact of government procurement on enterprise technological innovation and its' industrial differences. The results show that government procurement in China has played a significant role in promoting enterprise technological innovation in general, but there are significant industry differences in this effect. After considering the endogenous problems caused by self-selection of the samples, the conclusions of this paper are still valid. Therefore, in order to give full play to the technological innovation effect of government procurement, we should establish the concept of innovative government procurement, steadily improve the scale, opening and fairness of government procurement, strengthen the accuracy and effectiveness of government procurement, and implement the multi-dimensional methods for government procurement.

Key words: government procurement, technological innovation of enterprises, industry differences
