Research on the impacts of ports' construction on regional economic development

The integration of regional economic whose rapid development increase the construction speed and scale of the port of economic zone is becoming the main trend of China's economic development. In addition, the development and construction of the port has also contributed to the long-term healthy development of the regional economy. This paper establishes a model to analyze the complex relationship between the port' construction and regional economic development. The paper selects seven ports in different area including ports of Shenzhen, Dalian and Shanghai etc. as objects to study, carrier capacity, operating data and the corresponding macroeconomic data in the region within 10 years of ports as a data source, and the cross-sectional data model to analyze raw data obtained. The research results show that the port capacities will impact regional economic development and regional economic development will affect the speed and scale of the construction of the ports. But the interaction effect of ports' construction conditions and regional economic development speed have time lag, and the growth rate of port building scale are more than the expected level of regional economic development result in excess capacity of part of the ports.
