Abstract

The paper analyzed the specialization characteristics of cities in the Yangtze River Delta region from 2003 to 2017, and verified the influence of high-speed railway on the level of specialization by using DID method. It is found that: (1) the opening of Shanghai -Nanjing-Hangzhou in 2007 and Shanghai -Nanjing-Hangzhou High-speed Railway in 2011 have obviously promoted the specialization level of knowledge-intensive industries in cities along the Yangtze River Delta; (2)due to the difference in the ability to absorb knowledge, the opening of Shanghai -Nanjing-Hangzhou railway promotes the improvement of the specialization degree of the financial industry, while the improvement of the specialization level of other industries is not obvious
