基于引力模型與軸輻理論的省域物流網(wǎng)絡(luò)構(gòu)建研究
[Abstract]:Since the 13th Five-Year Plan, with the acceleration of economic globalization and the rapid growth of e-commerce, the logistics cost has risen due to the lack of unified planning in provincial logistics, and the unreasonable distribution of logistics resources has emerged. Moreover, the research on the determination of regional logistics axle point and hinterland is lack of scientific, objective and applicable research methods. Therefore, this paper proposes a method of combining gravity model with multi-hub hybrid axis-spoke logistics network to construct the logistics network in the province. In this paper, the concepts, types and structure characteristics of regional logistics network are analyzed, and a hybrid axis-spoke network with multi-hub is proposed. Based on the theoretical analysis of regional axis-spoke logistics network, the gravity model is introduced to determine the "quality of logistics" by entropy weight TOPSIS method. By using the K-means cluster analysis, the cities in the province are classified, and the hub cities of the axis-spoke point in the province are established. The gravity intensity between cities is calculated by the method of weighted formula, the membership degree of logistics among cities in the region is calculated by using theory, and the range of axis center, point of spoke and the hinterland of each axis city is further confirmed. Finally, the provincial logistics network is established by using the theory of multi-hub hybrid axle and spoke, and the logistics network is optimized. Taking Anhui Province as an example, taking the 2015 section data as the sample, the paper establishes the evaluation index that affects the competitiveness of the urban logistics in the province, and then obtains the size of "logistics quality". Based on gravity model and hybrid axis-spoke theory of multi-hub, this paper applies entropy weight TOPSIS and logistics membership principle to the logistics competitiveness of cities in the province, and finally determines that five cities such as Hefei, Wuhu, Fuyang, Bengbu and Anqing are the axis cities. Also can be called logistics hub city. The main frame of the logistics network of Anhui Province is constructed, and the regional logistics network system of Anhui Province is formed by establishing the connection between the axis city and the radial city and the two strong gravitational channels. It enriches and defines the empirical scope of gravity model and axis-spoke theory, and provides scientific basis for establishing and integrating regional logistics resources for micro logistics nodes such as logistics center, logistics park and so on.
