自由贸易港创新政策对港口运输的溢出效应OA

To thoroughly investigate the spillover effect of Free Trade Port(FTP)innovation policies on port transportation,taking Hainan Free Trade Port as the research object,this paper analyzes the impact mechanism and actual effect of Hainan FTP innovation policies on the transportation of Beibu Gulf Port by employing a comprehensive approach that integrates qualitative and quantitative analysis,as well as theory and practice.Through systematically sorting out the innovation policies of Hainan FTP in the field of port transportation,this paper discusses the impact mechanism and paths of these policies on Beibu Gulf Port's transportation.It considers that the appearance of spillover effect of Hainan FTP innovation policies on the transportation of Beibu Gulf Port is manifested as the driving role of the internal ports of FTP on the transportation of external ports.In the empirical analysis part,this paper selects monthly throughput data of the main cargo categories of Beibu Gulf Port and Hainan ports to build a panel data model to quantitatively measure the differential impact of Hainan FTP innovation policies on different cargo categories and ports of Beibu Gulf Port.The results show that:①The innovation policies of FTP have significant regional spillover effect,not only promoting the development of internal ports,but also driving the growth of surrounding ports' transportation through mechanisms such as industrial linkages and logistics coordination;②The spillover effect of these policies exhibits heterogeneity across cargo categories,with high value-added cargo benefiting more significantly,while bulk cargo is less affected by the policies,indicating that FTP policies tend to promote the development of high value-added logistics;③The spillover effect of the policies shows port heterogeneity,with ports that have obvious location advantages and a high matching degree of function position benefiting more,while ports with low matching degree of function position or more distant location experiencing relatively weaker spillover effects.This study provides valuable reference for the collaborative development of surrounding ports with the leverage of FTP policies.
