摘要

Under the general equilibrium framework, this paper draws on the method of Donaldson & Hornbeck (2016), uses the high‐speed rail opening data, estimates the transportation cost between the two cities, constructs the market accessibility index of each city, and accurately measures the Direct and indirect effects of high‐speed rail network on urban innovation. Using the panel data of 274 cities from 2009 to 2018, this paper examines the mechanism path of the change of market accessibility caused by the opening of high-speed rail, which leads to the improvement of urban innovation level. The empirical research finds that: 1. The market accessibility caused by the opening of high‐speed rail in major cities The increase in the level of sexuality has significantly and steadily boosted the level of urban innovation. 2. The innovative improvement of market accessibility has the heterogeneity of initial transportation infrastructure and economic development level. Cities that have not opened high‐speed rail also benefit from the overall effect of the opening of high‐speed rail, and the level of urban innovation has been improved. 3. Market accessibility can improve urban innovation through talent agglomeration and economic agglomeration. These research results will help my country to provide reference for narrowing the urban development gap under the dual background of implementing innovation‐driven and vigorously developing transportation infrastructure.
