PurposeLogistics capability is an important enabler of supply chain resilience (SCR). However, few studies have analyzed the underlying influence mechanism of logistics capability on SCR in extreme conditions, such as those of the COVID-19 pandemic. The purpose of this study is to increase understanding of the role of logistics capabilities in constituting a resilient supply chain.Design/methodology/approachDrawing upon the dynamic capability perspective and contingency theory, the proposed conceptual framework aims to demonstrate the relationship between a firm's logistics capabilities and SCR. Furthermore, the conceptual framework is illustrated by empirical evidence from a case study of a Chinese manufacturing company, which focuses on extracting practical lessons from the COVID-19 pandemic.FindingsThe findings suggest that digitalization, innovativeness, and modularization comprise potential mediating pathways for firm logistics capability to affect SCR and government policies, risk management culture, trust and cooperation moderate the effect positively. The potential associations are identified and elucidated by detecting the corresponding strategies and practices of a Chinese manufacturer that performed well amid the COVID-19 pandemic.Practical implicationsThis study provides specific guidelines for logistics managers to enhance SCR during the COVID-19 pandemic. Seeing SCR as a dynamic capability, the framework is also instructive for manufacturers, supply chain members, and policymakers to achieve the sustained competitive advantage of supply chains.Originality/valueThe findings expand the understanding of enhancing SCR in a logistics approach. The empirical validation of propositions in the case study reveals a new vista for research on SCR.

Entrepreneur is the driving force of survival and development of the small and medium-sized enterprises (SMEs), and is one of the most important factors which affect the vitality of SMEs. In this paper, we discussed entrepreneurs' own accomplishment of knowledge and practical experience, social networks (relationships between entrepreneurs and external stakeholders), cohesion of entrepreneurs (relationships between entrepreneurs and internal employees) and so on. This empirical study on the relationships between these 3 dimensions, 4 elements and SMEs' vitality was conducted based on 267 Chinese SMEs. The results show that practical experience, accomplishment of knowledge, cohesion and social networks play a positive role in promoting the continuous growth of the SMEs, and have a positive effect on SMEs' vitality.

The sandbank is a potential huge land resources, especially for land nervous regions, however, it has a very important realistic significance. So it becomes more important for sandbank shoreline's rapid monitoring, extraction and changing analysis . For the rapid extraction of sandbank shoreline of Jiangsu, China. Wavelet transform will be used first to process TM image. Then, on the basis of analyzing the gray value in each band of TM image, spectrum-photometric method will be used to pick up water body. And then generate a binary image, and carries on the non-directional edge enhancement processing. Last, generate a vector image of sandbank shoreline. By this method ,we can improve the computer processing speed, and, it is useful for treatment of mass data of multi-temporal and wide range. In addition, also greatly shorten the time of artificial extraction and reduce the error caused by artificial subjective.
