【目的】在"共同擁有而不占有"的共享經濟理念下,探索如何優化供需方的服務。【方法】爬取"小豬短租"的用戶數據,利用二模網絡分析工具Ucinet探究用戶位置演變,結合一模網絡中用戶復雜關系,構建固定效應模型分析個體中心度對相連用戶交易行為的影響程度。【結果】度數中心度會正相關顯著影響相連用戶行為,而房東中介中心度顯著影響房客消費行為,核心房客中介中心度顯著影響房東訂單供應行為。【局限】主要針對互動性強的用戶采取滾雪球抽樣,無法完全體現整個關系網絡的特點。【結論】為了促進小豬短租因交易行為構建的社會網絡活躍,應鼓勵用戶充當消費者,并主動參與其中作為服務提供商。

[Objective] This paper explores the service optimization methods based on the concept of "shared ownership without possession" of the sharing economy. [Methods] First, we retrieved data from the website of "xiaozhu short-term rentals". Then, we used the 2-mode network tool "Ucinet" to analyze the changing of users' locations. Third, we studied the impacts of individual centrality on users' behaviors through the fixed effect model and the relationship among the one-mode network users. [Results] We found that degree centrality positively influenced users' behaviors. The betweenness centrality of the host agents was negatively correlated with the consumers' behaviors, while the betweenness centrality of the key tenant agents positively affected the hosts' offering behaviors. [Limitations] We focused on active users, and did not investigate the characteristics of the entire network. [Conclusions] Business social network systems like xiaozhu.com should encourage their users to become both consumers and service providers, which will promote the development of Sharing Economy.
