Under the background of rural revitalization and development, the collective presence, value recognition, and action choices of villagers towards rural public welfare undertakings directly affect the actual effectiveness of various project constructions. With the social changes, rural communities are showing a trend of loose development, and the atomization and dissociation of individual villagers are not conducive to the continuous promotion of rural public welfare construction. With the application of digital technology, village WeChat groups have important value in breaking down time and space barriers, shaping value consensus, and aggregating collective action. Through the reorganization of participating subjects, awareness, and actions, the application of village WeChat groups promotes the extension of participation space in rural public welfare construction.

Drawing upon Chinese A-share listed companies from 2009 to 2021 as research sample, the impact of digital transformation on firms’ sustained green innovation was explored. It is found that digital transformation significantly promotes firms’ sustained green innovation inputs and outputs, and this conclusion still holds after a series of robustness tests. Heterogeneity analyses results indicate that the contribution of digital transformation to firms’ sustained green innovation varies according to the nature of firms’ property rights and the type of industry. The role of information asymmetry, and investor focus in this relationship was further analyzed. The results show that information asymmetry partially mediates the effect of digital transformation on firms’ sustained green innovation, while investor focus play a moderating role.

Aiming at the problem of profit distribution in a double closed-loop supply chain with manufacturers(M), recyclers(R) and ladder utilizers(T) as the main body, centralized decision-making, decentralized decision-making, MR decision-making and RT decision-making models were constructed. The optimal solutions for the supply chain members through the Stackelberg game were analyzed. The Shapley value was improved based on the three influencing factors, and the improved Shapley value was utilized to redistribute the profits of the supply chain’s participating bodies.The results show that the cooperation among supply chain members can effectively improve the overall profit of the supply chain and the profit of the members, low-capacity batteries have a high cost advantage, realizing a win-win situation in terms of profit and the environment, the profit distribution scheme proposed by improving the Shapley value increases the profit of the ladder utilizers, improves the cooperation of the ladder utilizers and the ladder utilizing motivation, and promotes the fairness of profit distribution in the supply chain and the stability of the supply chain cooperative alliance. It promotes the fairness of supply chain profit distribution and the stability of supply chain cooperative alliance.

The emergence of innovation research and development institutes is the product of China’s continuous improvement of innovation system construction under the background of implementing innovation-driven development strategy, which has played a huge role in promoting regional innovation cooperation and the transformation of scientific and technological achievements. Based on a total of 1 461 patents of 23 innovative R&D institutes in Tianjin, social network analysis was used to study the innovation cooperation of innovative R&D institutes and the transformation of scientific and technological achievements,. The results show that Tianjin has most independent R&D institutions, and the innovation ability gap between institutions is large.The innovation cooperation between institutions shows the characteristics of collectivization, and regional innovation cooperation needs to be improved. The conversion rate of scientific and technological achievements of institutions is much higher than that of general university research institutes. On this basis, targeted suggestions are put forward in order to provide reference for the government to formulate relevant policies.

As an important part of the strategy of comprehensively promoting rural revitalization, it is crucial to give full play to the organizational aggregation role of village cadres and effectively guide the participation of new social capitals formed mainly by new agricultural management subjects. Based on the questionnaire survey data from 19 provinces, the mechanism of village cadres in promoting the willingness of new social capitals to participate in rural construction actions was analyzed by using a binary Logit model. The results show that village cadres can significantly promote the willingness of new social capital to participate in rural construction through the role of organizational aggregation in shaping their own credibility and collective consensus formation. In terms of effect, the role of village cadres has a significant positive impact on the willingness of new social capital to participate in projects that are closely related to their personal interests, as well as on the willingness of new social capital subjects in less-developed areas.
