Based on the reality of safety production in manufacturing enterprises and the background of industrial Internet, a tripartite evolutionary game model of industrial internet safety production supervision platform-manufacturing enterprises-government was constructed to analyze and verify the stability of the system’s evolutionary strategy. The effects of the commission coefficient paid by the manufacturing enterprises, the development and operating cost coefficient of the platform, and the amount of fines imposed by the government on the platform on the evolution results are studied. The results show that increasing the commission coefficient paid by manufacturing enterprises can improve the probability of the platform choosing a high degree of safety production supervision service level and the probability of manufacturing enterprises choosing to join the industrial Internet safety production supervision platform. Reducing the development and operating cost coefficient of the platform can improve the probability of the platform choosing a high degree of production safety supervision service level. Increasing the amount of fines imposed by the government on the platform can improve the probability of the platform choosing a high degree of production safety supervision service level, and the probability of the government choosing to actively regulate the industrial Internet production safety supervision platform.

The top five research countries are the United Kingdom, the United States, Germany, China, and the Netherlands.From high impact literature,technological innovation,fairness and justice are topics that have received more attention, while the factors affecting energy transition have been a hot topic in recent years. From the perspective of keywords, research hotspots have changed rapidly, shifting from government functions in energy transition to multi driven research of “technology-policy-public”,from single transition target research to collaborative research on energy transition and multiple objectives such as fairness and justice, economic growth, and social change. Therefore, in the future, attention should be paid to interdisciplinary and comprehensive research on energy transition, multi-objective collaborative research, key technology breakthrough research, and government market combination research, to enrich the grand narrative and theoretical system of energy transition in the Chinese context.

“A new development pattern with domestic circulation as the mainstay, domestic and international circulation mutually promoting”is a clear development blue print of the current and future. In this context, the development of local traditional pillar industries are confronted with opportunities and challenges. In order to achieve the transition from quantity catch-up to quality improvement, from factor-driven to all-factor upgrading, and from industrial scale expansion to industrial structure upgrading and transformation, some path were proposed, including the establishment of regional industry alliances, the setting of local industry quality certification standards, the enhancement of product quality, the improvement of assessment and risk control, and the soft power-driven flexible coupling of high-quality development momentum.

The safe operation of the airport is the cornerstone of civil aviation safety. An airport operation risk assessment system was constructed to assess the safety risks of airport operation. It also identifies and eliminates the risk factors and safety hazards in advance. Firstly, using the theory of man-machine-environment-management, the airport operation safety evaluation system was established. Then, using the analytic hierarchy process and the entropy method, the data obtained from the two methods was analyzed and compared, and the weighted comprehensive calculation was carried out to obtain the comprehensive weight of each indicator. Finally, the risk assessment method established in the paper was used to conduct a risk assessment test of the operation of Yuncheng Yanhu Airport. The test results show that the research method in this paper is feasible and effective.

Industrial policy is an important driver of industrial development. Taking the Shuangcheng Economic Circle of Chengdu-Chongqing area as the research area, an in-depth study on the driving effect of industrial policy was conducted based on knowledge graph technology, in order to clarify the important role of industrial policy in promoting industrial structure optimization, regional balanced development and economic transformation and upgrading. The industrial policy knowledge map of the region was constructed based on regional differences, time evolution characteristics, policy orientation and other core factors. Then, combining with the comprehensive industrial development level of the region, the visualization and retrieval functions of the knowledge map were utilized. The PMC I(policy modeling consistency) index was used to evaluate 496 policy samples, and the driving effect and driving mechanism of industrial policies were further analyzed. The results show that the industrial development trend in the study area is stable and good on the whole, and the PMC composite index scores of industrial policy samples in all regions have reached an acceptable level or above. Among them, the essence of policy content, the ability of forward-looking planning and the construction of guarantee and incentive mechanism are the core elements of the driving effect of industrial policy. Accordingly, countermeasures and suggestions are put forward from the perspective of policy optimization and perfection, evaluation and adjustment.

In recent years, continuous support from the central government has been provided, resulting in remarkable progress being achieved in digital infrastructure construction in ethnic regions. Based on the panel data from eight ethnic regions spanning from 2013 to 2022, a two-way fixed effect regression method was used to analyze the impact of digital infrastructure on rural industrial integration and to explore its mechanism. The empirical results now show that digital infrastructure has a significant positive impact on rural industrial integration. Agricultural loans, as an important part of financial services, are found to play a partial mediating role in this process. Therefore, it is necessary to strengthen the construction of digital infrastructure in ethnic regions and actively promote the development of rural digital inclusive finance.

With the booming development of digital economy, as the core force to promote the transformation of the insurance industry, insurance technology has become the focus of attention in academic circles.
