Abstract
The logistics industry is likened to be the “catalyst” of economic growth. It is one of China’s top ten key revitalization and adjustment industries, and port logistics is the main force to promote regional logistics and regional economic development. This paper, which is based on the niche theory and its corresponding measurement method, establishes the niche evaluation indicator dimension of the development competitiveness of port logistics in the Yangtze river delta. In this paper, the niche width model, niche overlap model, niche suitability and evolutionary momentum model were used to conduct an empirical study on the development competitiveness of nine typical ports in the Yangtze river delta region from 2013 to 2017. Finally, according to the expansion of ecological niche, the separation of ecological niche and the symbiosis of ecological niche, the paper put forward the suggestions for the sustainable development of port logistics in the Yangtze river delta region.

Evolutionary Momentum Evolutionary momentum characterizes the intensity of the effect of realistic niche of port logistics on the trend of its optimal niche
Summary
Economic globalization, trade liberalization and transportation integration have enabled the rapid development of port logistics. At present, the coordination degree of port logistics in the Yangtze river delta region is not high, and the regional differences are large. It is important to evaluate the logistics competitiveness of Yangtze river delta ports. The niche width of port logistics refers to the actual range or potential capacity of port logistics to adapt to the environment and utilize resources. In this paper, it can be understood as the degree of each port’s occupation of the same logistics resources. The wider the niche, the greater the degree of logistics resources occupied by the port, the better the development environment, and the higher the efficiency of resource utilization. In Formula (1), Ai is the niche breadth of i port logistics; Pij is the utilization rate of i-th port to logistics resource j, and M is the total amount of logistics resources owned by the nine Yangtze river delta ports
