Port-city synergism and regional development policy: Evidence from the Yangtze River Region

초록

As one of China's three development strategies, the Yangtze River Economic Belt (YEB) strategy plays an important role in strengthening the development of port–city synergy. This study uses the difference-in-differences (DID) approach to investigate the impact of the YEB strategy on port–city synergy development, with panel data for 15 port–city pairs along the YEB over the period 2005–2019. The results show that the YEB strategy significantly promotes port–city synergy through fixed-asset investment in the transportation, warehousing, and postal industries, especially for economically developed port cities and cities far from the port. It is suggested that decision-makers prioritize the fixed asset investments in these industries and formulate differentiated collaborative development plans according to different types of cities. © 2024
