Taking A-share listed companies from 2008 to 2021, it is found that the application of AI has a significant positive impact on the outward foreign direct investment(OFDI), and the conclusion is still established after relevant tests. The results show that the impact of AI application on enterprise OFDI is mainly realized through three ways: improving enterprise total factor productivity, reducing financing constraints and increasing overseas executives. For enterprises in the eastern region, state-owned enterprises and non-high-tech enterprises, the impact is more obvious.Empirically verifies the positive role of AI application for Chinese enterprises in opening up to the outside world, which has important enlightenment to promote enterprises to better “go out”.

In order to explore the disturbance mechanism of shield construction on composite strata,taking the coastal composite strata as an example, and relying on the Fuzhou Coastal Line, the disturbance mechanism of shield tunneling in composite strata was investigated.A refined numerical model of shield tunneling was established based on the finite element analysis software ABAQUS, and four parameters were considered, including face support pressure, grouting pressure, jack thrust, and cutterhead torque. After validating the model with on-site monitoring data, the settlement patterns of five composite strata traversed by the shield tunneling in the actual project were examined. The results show that the closer to the excavation area of the shield machine, the greater the disturbance; when the tunnel passes through composite strata, it causes more significant cutting in the softer layer, increasing soil disturbance.

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.

Taking A-share listed companies in China from 2009 to 2022 as a research sample, the relationship between ESG(environmental, social, and governance) practice and new quality productivity of enterprises was explored. It is found that strengthening ESG practice can significantly improve new quality productive forces of listed companies in China, and the conclusion is still valid after the robustness test. Enterprise ESG practice can help to improve new quality productive forces by alleviating financing constraints, reducing enterprise risks and enhancing external supervision. The results of the economic consequences test indicate that enhancing the new quality productivity of enterprises has a positive impact on market value and operating gross profit margin.

A favorable business environment can effectively improve the level of digital economic development in provinces. It is of great research significance to optimize the business environment in order to promote the digital economy. Using the research method of fsQCA(fuzzy-set qualitative comparative analysis), the path of as sit in the development of digital economy in the business environment was analyzed from the perspective of configuration. It is found that a single business environment element does not constitute a necessary condition for promoting the development of the digital economy. The market environment, government environment, and the legal and policy environment plays a pivotal and essential role in fostering the advancement and growth of the digital economy. The construction of the market environment is significantly lagging behind due to its regional characteristics. In order to create a healthy market environment, it is necessary to create a relaxed market atmosphere.
