Abstract: The leading and leading role of private high-tech industries in production efficiency is conducive to the implementation of my country's innovation-driven strategy and the realization of high-quality economic growth.This paper uses the urban panel data of private high-tech industries from 2003 to 2013, and uses the dynamic spatial Dubin model to study the direct impact and spatial spillover effects of financial subsidies and advanced stage of industry structure on the production efficiency of private high-tech industries.The research conclusions show that: financial subsidies have a significant promotion effect on the total factor productivity and technical efficiency of private high-tech industries, but the impact on technological progress is not significant, and only has a significant positive spatial spillover effect on technical efficiency.Advanced stage of industry structure has a significant positive impact on all indicators of production efficiency, and also has a spatial spillover effect on production efficiency,and if there is a spatial spillover effect, the spatial spillover effect is much greater than the direct effect.

Key words: production efficiency, financial subsidies, advanced stage of industry structure, private high-tech industries
