Vulnerability and Influencing Mechanism of Open Economy-Outbound Traffic Composite System in Chinese Mainland
Under the background of expanding opening-up of Chinese mainland through international interconnection and transportation infrastructure,this paper constructs the vulnerability evaluation index system of open economy-outbound transportation system from the two dimensions of sensitivity and responsiveness,uses set pair analysis method to measure its vulnerability,and uses Theil index,spatial Markov chain and obstacle degree model to analyze its spatial difference characteristics,spillover effect and obstacle factors.The results show that:1)The vulnerability of the coupling system between the open economy and outbound traffic in Chinese mainland shows a circle structure with the central region as the core and gradually increasing along the border areas.The low-vulnerable cities show the characteristics of"cluster"distribution centered on urban agglomerations.The vulnerability of the central cities is the lowest,and the vulnerability of the border port cities is the highest.The vulnerability of the system decreases year by year.2)The spatial difference of system vulnerability is increasing year by year,and the contribution of intra-provincial difference is greater than that of inter-provincial difference.3)The type of vulnerability tends to remain the same,and the low-vulnerability cities have a significant positive spatial spillover effect.4)Dependence on foreign trade and foreign capital,minimum travel time of outbound transportation,freight turnover,total import and export trade are the main obstacles to reduce vulnerability.The research conclusions can provide decision-making reference for Chinese mainland to achieve high-quality and sustainable development of open economy by relying on the opening channel.
