The construction of high-speed rail engineering brings not only the convenience of lifestyle,but also accelerates the flow of talents,capital and other resource elements,thus promoting the improvement of corporate performance.This paper takes the four vertical and four horizontal high-speed railway lines constructed in 2009-2014 as a quasi-natural experiment,adopts the double difference model,and introduces enterprise innovation management as an intermediary variable to examine and evaluate the economic effects brought by high-speed rail engineering construction to enterprises from a microscopic point of view.The results show that the construction of high-speed rail projects mainly improves the management performance of enterprises by promoting the flow of talents and stimulating the innovation management of enterprises.The conclusions of this paper help to deepen the analysis of the economic effects of high-speed rail construction,and provide a reference for the country to further accelerate the construction of high-speed rail and promote the regional economic development with the help of high-speed rail construction.
