The purpose of the paper is to find the influencing factors of the regional logistics spatial structure and propose suggestions to stimulate the vitality of the regional economy. Taking Sichuan Province as an example, this paper uses principal component analysis to improve the gravity model to measure the logistics gravity between cities. Use the social network analysis method to calculate the regional logistics spatial network correlation structure in Sichuan Province from 2010 to 2018. The QAP analysis method is then used to identify the factors that affect the development level of regional logistics specialization. The research results show that the logistics relationship between cities has become closer from 2010 to 2018, but network resilience needs to be strengthened. The division of blocks is the same as that of the five major economic regions of Sichuan Province, but there is an urgent need to enhance cooperation between plates. The correlation coefficient between the level of logistics specialization and the degree of betweenness centrality is not significant, indicating that the logistics mode of node cities is single, and the informatization and standardization need to be improved.
Recycling spent power battery is an important measure to alleviate energy shortage and environmental pollution. However, at present, there is no uniform standard for the recycling channels of spent power battery, and the construction of recycling channels of various recycling subjects is chaotic, and the mode with the highest efficiency is still inconclusive. Therefore, based on the current situation of spent power battery recycling, combined with the closed-loop supply chain channel decision-making theory, this paper studies three hybrid dual-channel recycling modes, compares and analyses the recycling rate and profit under different modes, and finally discusses the influence of different factors and recycling modes through numerical analysis. The results show that: (1) The hybrid dual-channel recycling mode of automobile alliance and third-party recycler can bring the maximum recovery rate and profit. (2) The competition between different recycling channels can not only improve the recovery rate, but will lead to the decline of the recovery rate and profit, resulting in a double loss situation. (3) Centralized decision-making brought about by cooperation can improve the total recovery rate and the total channel profit.
