In order to solve the safety problem of aviation dangerous goods transportation, under the perspective of social responsibility, a three-party evolutionary game model with the subjects being the government, airlines and shippers was constructed, and the strategy choices under different conditions were analyzed. MATLAB was used to numerically simulate the important parameters to explore the effects of the sensitivity changes of the penalty, the government’s active regulation cost, the success rate of active regulation, the airline’s violation revenue and the shipper’s management cost on the evolution of the system. The results show that the government’s penalty and the success rate of active regulation are positive incentives for shippers and airlines, and the government should increase the penalty in order to effectively solve the safety problem of air dangerous goods transportation.

The delay diffusion phenomenon caused by large-scale flight delays has a significant impact on air traffic networks. In order to better predict and control delay diffusion, a delay diffusion prediction model combining convolutional neural network (CNN) and traditional epidemiological SEIR(susceptible-exposed-infectious-recovered) model is proposed for the nonlinear and complex characteristics of flight delay diffusion, as well as for the difficulty of combining real-time and accuracy. Based on the flight delay diffusion propagation mechanism and SEIR model, a flight delay diffusion dynamics model was established, and the key parameters in the model are optimized by convolutional neural network. The optimized model was simulated using MATLAB, and the accuracy was improved by 17.95% compared with the traditional SEIR model after combining the CNN model.

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.

In the era of digital economy, smartphones have become an indispensable tool for modern people.However, the silver-haired people often face the problem of “difficult to use” when using smartphones and other intelligent products. In order to study the impact of smartphone use on the subjective well-being of the elderly, a questionnaire survey and field visits were conducted among the elderly in some areas of Hunan Province, and the happiness-related statements in the survey data were extracted, and descriptive statistical analysis, correlation analysis and regression analysis were used to determine the factors that affect the subjective well-being of the elderly as well as the well-being score index. The results show that the use of smartphones has a positive impact on the subjective well-being of the elderly, which not only improves the quality of life of the elderly and promotes their enjoyment of the technological dividends of the times, but also facilitates the work of active aging and the comprehensive development of society.

Different types of leadership utilizing signaling strategies in a digital context can have different impacts on employee breakthrough creativity. Drawing from the signaling theory, 288 samples of leaders and subordinates from governmental departments in Southwest China were examined to explore the influence mechanisms of ethical leadership and mindful leadership on employees’ radical creativity, and the predictive effects on radical creativity were compared. The results show that ethical leadership and mindful leadership foster employees’ radical creativity, ethical leadership has a higher predictive effect on employees’ radical creativity than mindful leadership, artificial intelligence awareness negatively moderates between the two leadership styles and radical creativity, respectively.

Digital economy level evaluation system and Guangzhou urban-rural integration level system were constructed to further calculate the digital economy level and urban-rural integration level in Guangzhou. The following results are obtained: digital economy has a significant positive impact on promoting the integrated development of urban and rural areas in Guangzhou.The improvement of human capital level, urbanization level, the increase of agricultural expenditure, and the narrowing of the gap between urban and rural Engel coefficient can all promote the development of urban-rural integration in Guangzhou, However, although the coefficient of the network traffic density is positive for the urban-rural integration of Guangzhou, But the effect is not obvious.Digital economy promotes the coordinated development of urban and rural areas in Guangzhou through its economic development, capital flow, rural industry revitalization, social security and equalization of public services.

Promoting the coordinated development of high economic quality and ecological protection in the Yellow River Basin of Shandong Province is conducive to realizing the goal of “double carbon” in the region. Based on the panel data of the Yellow River Basin urban agglomeration in Shandong Province from 2015 to 2022, a coupling coordination degree model of economic high quality and ecological protection was constructed and an empirical analysis was conducted to explore the coordinated development relationship between the two. The results show that the development level of high economic quality and ecological protection in the Yellow River Basin of Shandong Province is on the rise. The regional coupling coordination level showed a trend of “moderate coordination-high coordination”, the distribution of each urban area was uneven, and the coupling coordination type showed a trend of “low imbalance-moderate coordination-high coordination”. In the analysis of driving factors, the full-time equivalent of R&D personnel, the number of authorized applications for three kinds of domestic patents, and the application amount of agricultural fertilizer have significant hindrance.

The development of new quality productivity is the internal requirements and important focus of promoting high-quality economic and social development. Private enterprise plays an important role in the development of new quality productive forces. private enterprise has strong innovation vitality, which can provide impetus for the innovative allocation of production factors and the revolutionary breakthrough of technology. At the same time, the development of new quality productivity of the private enterprise is also facing the problems of limited access to factors, high cost of factors, and the weakening of development expectations, which affects the role and advantages of the private enterprise. To this end, it is necessary to continue to increase policy efforts to support the private enterprise, and build a bridge of mutual trust between government and enterprises, a bridge of mutual promotion of social enterprises and a bridge of mutual integration of the production chain.

Based on the analysis of development potential and positioning, the planning and layout were carried out with a focus on the Baituan Battle Site Park. Finally, research on marketing methods and security measures was conducted. The research results indicate that tourism resources are abundant and have enormous development potential in Yangquan. The planning layout is operable. The implementation of marketing methods is strong and the guarantee measures can fully ensure sustainable development.

An evaluation index system for agricultural science and technology (S&T) innovation capacity and agricultural high-quality development was constructed using the entropy method. By integrating these indices with a binary system coupling coordination degree model, the coupling degree and coupling coordination degree for provincial-level administrative regions from 2010 to 2020 were calculated. It is found that the agricultural S&T innovation capacity and the comprehensive index of agricultural high-quality development have shown a significant upward trend since 2010, reflecting the thorough implementation of the innovation-driven development strategy in the agricultural sector. The comprehensive index of agricultural high-quality development displays a distinct regional hierarchy: east > central > west > northeast. The eastern region leads in agricultural S&T innovation capacity, followed by the central and northeastern regions, with the western region showing relatively weaker innovation capacity. While the interaction between agricultural S&T innovation capacity and agricultural high-quality development is strong, the depth of this positive interaction remains limited. The system coupling degree has gradually increased and is nearing 1, indicating more frequent interactions between the two systems. However, the coupling coordination degree is significantly lower than the coupling degree, suggesting that the positive interactions between the systems are insufficient, and the potential synergies between them have not been fully realized. In response, several policy recommendations are proposed, including accelerating new quality agricultural productivity, improving the institutional mechanisms for agricultural S&T innovation, capitalizing on the advantages of the burgeoning digital technology sector, and advancing the development of smart agriculture.
