| The logistics industry is a comprehensive service industry with functions of information,processing,warehousing,transportation and distribution.Its development history is closely related to the macroeconomic environment.It is a strategic,leading and fundamental economic operation of the Pearl River-Xijiang Economic Belt.industry.The advanced form of logistics industry development is to form a logistics industry cluster,which is a key link to realize the modernization of the logistics industry.The characteristics of the cluster determine the economic effect and competitive advantage of the logistics industry,that is,the logistics industry further forms after a certain regional cluster.Competitive advantage and clustering effect.Therefore,it is an urgent problem to accelerate the development of the logistics industry in the Pearl River-Xijiang Economic Belt.Based on the relationship between logistics industry cluster and logistics technology efficiency,this paper takes the panel data of 11 cities in the Pearl River-Xijiang Economic Belt fr-om 2006 to 2017 as a sample to analyze the technical efficiency and spatial effect of the logistics industry cluster in the Pearl River-Xijiang Economic Belt.In-depth research was conducted.Firstly,the concept,formation mechanism and interaction mechanism and technical efficiency of logistics industry cluster are expounded.Secondly,based on the development status of economic logistics industry,the improved location entropy index is introduced to analyze the logistics industry of economic belt.Cluster degree and spatial correlation;the stochastic frontier model(SFA)is used again to analyze the technical efficiency of logistics cluster degree,and the convergence of technical efficiency is tested.The spatial spillover effect of economic cluster logistics industry cluster is constructed by constructing space Dubin model.Empirical analysis;Finally,by summarizing the research conclusions,further propose policy recommendations to effectively promote the technical efficiency of logistics industry clusters.The study found that the logistics industry of the Pearl River-Xijiang Economic Belt has progressed to a stage of high stability and quality improvement.First,there is a spatial cluster phenomenon in the inter-regional logistics industry in the economic zone.At the same time,the logistics industry clusters in the economic belt show a significant positive spatial correlation.However,the degree of clustering between cities is quite different.Secondly,as a whole,the technical efficiency of economic logistics clusters is still at a low level,with relatively obvious stratification and a large room for improvement.When introducing the interaction between industry clusters and employment numbers and industries in the model After the interaction between clusters and fixed asset investment,the technical efficiency of logistics industry clusters in various cities in the economic zone has been improved.Thirdly,in terms of the spatial spillover effect of logistics industry clusters,the results show that the logistics industry clusters in the Pearl River-Xijiang Economic Belt have positive externalities,namely positive spatial correlation and spatial dependence,rather than spatial competition.Fourth,the efficiency level of economic logistics clusters is not only affected by the production factors invested in the region,but also by the diffusion of external efficiency and the positive externalities such as radiation. |
