With the rapid development of information technology and the rise of the Internet+ era, the sharing economy has fundamentally changed people's lives and consumption patterns, and has also reshaped the process of value co-creation between enterprises and customers. In the sharing economy, enterprises no longer play the dominant role; instead, they have evolved into platforms that provide support and services for users. In this economy, users not only determine the profitability and reputation of enterprises but also create substantial value through the exchange of usage rights to idle resources and interactions both online and offline. Therefore, studying the value co-creation behavior of bilateral users on sharing service platforms is of significant necessity for enterprise development. This research aims to explore the impact mechanism of bilateral user value co-creation on customer value in sharing service platforms. Through the analysis and summarization of literature, a theoretical model of bilateral user value co-creation and customer value in the context of the sharing economy has been established. The research subjects include users of the homestay/inn platform on Ctrip, as well as users of other types of sharing platforms, such as Lazy Housekeeping, LoveChef, Didi and Airbnb. In the empirical part, questionnaires were designed and sample data was collected through the Questionnaire Star platform. SPSS 25 and AMOS 23 data analysis software were used to perform reliability and validity analysis and correlation analysis of the scales. Multivariate regression analysis was employed to investigate the impact of bilateral user value co-creation on various aspects of customer value. Additionally, the Bootstrap method was used to test the mediating roles of relevant factors. Through the above research methods, we will be able to have an in-depth understanding of the impact mechanism of two-sided user value co-creation on customer value of the shared service platform and obtain more comprehensive and concrete research findings. I believe that the findings of this study will have important implications for the theory and practice in the domain of sharing economy.

As the global economy and digital technology rapidly advance, the service industry faces increasingly intense market competition and challenges in meeting diverse customer demands. This study, set against the backdrop of chain hotels in China, empirically analyzes how service modularity could impact customer perceived value and contribute to innovation performance of hotels. Using two innovative prototypes from Jinjiang Hotels at different development stages as examples, both quantitative and qualitative research methods were employed to delve into the effects of service modularity innovation. For the “fit-up” module at the incubation phase, conjoint analysis was applied to understand consumer preferences and willingness to pay for the module combination, defining the product version 1.0. Regarding the “pure room” module at the pilot phase, structural equation modeling (SEM) was used to validate the relationship between modular innovation and perceived value, satisfaction, and consumer willingness, laying the foundation for optimizing and promoting version 1.0. Empirical results indicate that service modularity significantly enhances customer perceived value, enabling efficient personalized service innovation design to respond more rapidly to consumer demand iterations. Service modularity, as a crucial trend in service management, holds significant importance in improving service efficiency, meeting customer needs, and enhancing enterprise competitiveness. This study enriches the theoretical framework of service modularity and innovation performance, providing empirical evidence of its impact on customer perceived value and innovation performance. Furthermore, as an innovation management strategy, service modularity proves effective in enhancing the innovation performance and service upgrades of chain hotels, especially the mid-scale segment, offering meaningful insights and references to strengthen competitive advantages.

This study provides an in-depth investigation of customer management in the construction decoration industry, focusing on Shanghai A Construction Engineering Co., Ltd. By analyzing the company's operational data, the study emphasizes different ownership types of clients and examines factors influencing the profitability of high-quality client projects. The findings reveal that foreign-funded enterprise clients exhibit significant advantages in project quantity, profitability, and per capita output value within Shanghai A Construction Engineering Co., Ltd. While private and state-owned enterprises also have a certain number of projects, foreign-funded enterprises account for over 70% of the total projects. Moreover, the project profitability of foreign-funded enterprises is notably higher than that of the other two types. However, there is no significant difference in per capita output value among the three types of enterprises. Further regression analysis demonstrates that unique technologies and client-specific attributes have a significant positive impact on project profitability. This implies that enterprises with unique technologies and a deep understanding of client needs can achieve higher project profitability. Additionally, bidding quantities and contract amounts have a positive effect on per capita output value, indicating that participating in more bidding activities and securing high-value contracts can enhance project productivity. In conclusion, the research findings shed light on key aspects of customer management for small and medium-sized construction decoration enterprises. Foreign-funded enterprises possess advantages in project quantity, profitability, and per capita output value. Unique technologies and client-specific attributes have a positive influence on project profitability, while bidding quantities and contract amounts contribute to increased per capita output value. These research results provide valuable insights and guidance for small and medium-sized construction decoration enterprises to comprehend the importance of customer management and develop strategies to enhance profitability and performance. However, the specific implementation strategies need to be adjusted and optimized based on each company's unique circumstances to achieve the best outcomes.

The pharmaceutical industry is closely related to the national economy and people's livelihood, with high drug prices and pressure on health insurance. The implementation of the band purchasing policy has made an important contribution to lowering drug prices, improving the balance rate of health insurance, reshaping the pattern of the pharmaceutical industry, and improving the efficiency of pharmaceutical production and circulation, but how the band purchasing policy affects the performance of the majority of pharmaceutical enterprises, and how the pharmaceutical enterprises can effectively deal with the challenges of environmental mutation and other related problems have not yet been effectively explored.To this end, this paper collects data from A-share listed pharmaceutical companies in China from 2014 to 2022, takes 2018 as the base year for the implementation of the "4+7" "band purchasing" policy, and utilizes a multi-period DID double-difference model for hypothesis verification. It is found that the implementation of the band purchasing policy significantly reduces the profitability performance and growth performance of pharmaceutical enterprises. Secondly, the implementation of enhanced innovation can moderate the negative impact of band purchasing on the growth performance of enterprises, and the expansion of exports and the enhancement of digitalization can significantly ii improve the negative impact of band purchasing on the profitability performance of enterprises, but has no effect on the growth performance of enterprises. In addition, this paper analyzes the process of pharmaceutical enterprises' implementation of enhancing innovation, expanding exports, and improving digitalization through case studies, and refines the strategic change process model of "coping strategy formation - coping strategy implementation - adaptation to the new state" under the sudden change environment. This paper explores the differentiated effects of coping strategies of different types of pharmaceutical enterprises in the face of the band purchasing policy, and provides some insights into the practice of related enterprises.
