Evaluation of the Transportation in Investment Environment from Land-Sea-Air Coordination: A Case Study of Northeast China

Transportation network is an important link for economic cooperation between cities. It is of great significance to build a coordinated transportation network of land, sea and air to improve the service level of the international logistics supply chain and promote the coordinated development of land, sea and air economy. This paper takes northeast China as the research area, from the perspective of Land-Sea-Air Coordination. We consider comprehensive traffic accessibility in the evaluation of transportation in the investment environment. Qualitative indicators relating to convenience, construction scale and service level were selected to build a transportation evaluation index system in the investment environment using the entropy model. And then, we measure transportation in the investment environment and regional differences in northeast China. The results can deepen the scientific understanding of transportation in the investment environment in northeast China. The sea, land, and air resources can flow smoothly and complementary. Based on it, we can realize high-quality and efficient transportation in the investment environment construction. This study is of great significance to reveal the role of comprehensive transportation accessibility in the investment environment of transportation and improve the evaluation system of the investment environment.
