The logistics industry is a basic and strategic industry that supports the development of national economy and society. The purpose of this paper is to evaluate the logistics efficiency of 22 cities in Guangxi and Yunnan provinces in China, and to grasp the problems and constraints and present policy proposals to promote the transformation and upgrading of the industrial structure in Guangxi and Yunnan provinces. In this paper, five input indexes and four output indexes were selected and the data from 2016 to 2018 were analyzed through DEA method. According to the analysis, the logistics efficiency of Guangxi and Yunnan provinces is not bad overall, but the development of each region is not balanced and the level of logistics efficiency is quite different. And it is found that each city needs to further improve the level of scale because the input and production structure of logistics resources is unreasonable. The limitation of this study is that it is difficult to generalize the analysis results because only the data over the past three years have been analyzed. It is necessary to comprehensively implement longitudinal and transverse analyses by extending the future analysis period over a long period of time.

This study was done to analyze the effect of logistics services, corporate image, product reliability and customer service on consumer satisfaction and repurchase intention that e-commerce users perceive. The survey was divided into "logistics services, corporate image, product reliability, customer services, customer satisfaction, repurchase intention". As a study result, independent variables such as corporate image, product reliability and customer services were found to affect customer satisfaction. Consumer Satisfaction had an effect on repurchase intention in mediated and dependent variable. In conclusion, in order to increase the repurchase intention in companies that introduced SCM, it was necessary to improve the corporate image, product reliability and customer service to satisfy consumers. Logistics services had not been adopted as an impact on customer satisfaction. We should strive to improve customer satisfaction and repurchase intention by creating a higher level logistics services.

The selection of a third-party logistics (3PL) provider is a critical process for shippers who want to receive competitive logistics service. However, studies analyzing the factors that influence the selection of 3PL provider from the viewpoint of shippers are insufficient. The present study aims to derive factors to be considered when selecting a 3PL provider by domestic shippers and to present the weights of each factor. The analysis results showed that among the major factors, the "operation factor" showed the highest importance, followed by "strategic factor", and "communication factor". The results of compound weights showed that "cost reduction" is the most important factor, followed by the "expertise of the provider", "inventory management ability", and "human resources management". The present study proposed the core factors that should be considered when selecting a 3PL provider from the shipper's viewpoint. This study also has an industrial implication from the viewpoint of 3PL providers because it provides the basic data for enhancing the shipper's satisfaction by reinforcing the factors that are considered important in by shippers. In future research, it is necessary to classify shippers by industry and analyze the differences in the factors that arise in selecting 3PL companies for each industry.

This study examined whether relationship marketing activities affected relationship satisfaction and ultimately relationship continuity intention for 180 online store users. As a result of hypothesis test through path analysis, it was found that financial activities and structural activities such as delivery services in shopping malls had a positive effect on relationship satisfaction. In particular, it was found that the influence of structural activities was greater. This suggests that fast delivery or easy-to-search traffic is more meaningful to relationship satisfaction than economic benefits. At the significance level p<0.05, it was found that social activities did not have a significant effect on relationship satisfaction. Because it is not easy to develop social bonds between salespeople and customers at online stores, but the direction is considered positive. Therefore, if online stores can form social bonds with customers, this will have a positive effect on relationship satisfaction, but it is expected that this will become a factor that can differentiate them from competitors.
