| During the process"Input-Transfer-Output"of the regional economic, the regional logistics satisfies input demand and output demand of the materials in physical state, provides essential support for high efficient running of the regional economic. Meanwhile, the logistics industry which attributes to the third industry becomes an important component of the regional economic. The regional logistics interacts with the regional economic, the regional logistics development is beneficial to promote the increment of regional economic output, the development of other industries and the optimization of the industrial structure, and beneficial to optimize the development mode of regional economic, to shorten the income gap between different industries and between urban and rural areas, etc. The regional economic development is beneficial to generate stable service demand of logistics, to increase the investment scale for the construction of regional logistics, and the optimized structure of regional economic is beneficial to optimize the structure of regional logistics, etc.With continual expansion of economic activity scope, the logistics activity which provides necessary service for economic will not be confined in a fixed scope. For ensuring the system operation, the logistics industry will transfer products and materials, funds, logistics information between cities of the same region or between different regions, which expand the space interaction scope of regional logistics, will be beneficial to obtain more shares in a wider market and to attract more capital inflows.Most of related researches focused on the local influence correlation between regional logistics and regional economic, failed to describe how the two systems interacted from various aspects as a whole. The researches which evaluated the regional logistics neglected the importance of location factors for the regional logistics development; the researches which focused on space interaction, less involved the logistics connection between regions and the radiation intensity from one region to external regions owning to the development. Therefore, the paper utilized field theory to analyze regional logistics specifically from interaction angle as follows:First, combined with the development environment of China logistics industry in recent years, analyzed the background and signification for the subject selection. Based on the related researches on regional logistics development, field theory application, economic connections between cities and so on, summarized research status at home and abroad related to the theme, the main research contents, research methods, technical route and innovation points of the paper.Second, based on the location theory, regional logistics theory, field theory etc., the paper defined the regional logistics field, specifically analyzed its components and properties, compared it with physical field. Economic-effect and space-effect were put forward on the basis of the concept of field-effect of the regional logistics field.Third, analyzed the connotation of economic-effect of the regional logistics field from two aspects: one is the influence on regional economic from regional logistics, the other is the influence on regional logistics from regional economic. By comparing several measurement methods, determined to use canonical correlation analysis to measure the economic-effect which based on the panel data of 31 provincial regions from 2003 to 2008. Analyzed the economic-effect from global and local views on the basis of the measurement results, such as coefficients and values of canonical variants, canonical correlation coefficients and index correlation coefficients, etc.Fourth, analyzed the connotation of overall-effect of the regional logistics field which consisted of characteristics analysis, generation conditions, dynamic mechanism and types, etc. Constructed field source gravity model, potential models and status model, measured the overall-effect based on related data of 31 provincial field sources in 2008. Analyzed the connection intensity between field sources, interference ability, anti-interference ability and comprehensive ability of each field source.Fifth, analyzed the connotation of neighborhood-effect of the regional logistics field which consisted of characteristics analysis, generation mechanism, action forms, etc. By comparing several measurement methods and combined with basic breaking-point model, corrected and deduced breaking-point track model for measuring neighborhood-effect based on related data of 31 provincial field sources in 2008. Analyzed the radiation intensity and characteristics of each field source to the neighbor field sources, and compared the basic breaking-point model with breaking-point track model by the results.Sixth, based on results analysis about the economic-effect, overall-effect and neighborhood-effect, the paper proposed development countermeasures, included promoting logistics development by developing economic, optimizing infrastructures such as traffic network, activating logistics output capability, developing human resource effectiveness, strengthening the cooperation between departments and between regions, constructing logistics information platform, optimizing the potentials of field sources and seizing the opportunities in the competition and so on. |
