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.

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.

Taking regional airport in Henan Province and provincial airport group formed by Wuhan and Xi’an as the research object, the homogenization of regional airport development is studied. According to the characteristics of the airport, the form of the homogeneity of each dimension was deconstructed, the multi-dimensional index was established, and the homogeneity level of each characteristic index was measured. Taking four airport clusters in Henan as an example, the homogenization level was evaluated. According to the calculation results, ArcGIS software was used to draw the homogeneity level of regional airports in Henan Province. The findings reveal that Xinzheng Airport demonstrates high autonomy and international connectivity, whereas Nanyang and Luoyang airports, located in western and southern Henan, face issues of route similarity and identical airport positioning. Additionally, the close proximity between Nanyang and Xinyang airports hampers their expansion due to the limited scale of each city.Consequently, drawing from these outcomes, specific strategies for the coordinated development of Henan Province’s airports were proposed, in order to reduce homogenization according to airport positioning and urban development.

Shandong Province is a key implementation area of China’s rural revitalization strategy, and it is of great significance how to optimize the development system of digital inclusive finance so as to achieve high-quality development of agriculture. The evaluation index system of agricultural high quality was constructed, adopting the panel data of each prefecture-level city in Shandong Province from 2012 to 2021, the relationship between the two was empirically analyzed by using the two-way fixed-effects model and the spatial autoregressive model. The results show that the digital financial inclusion has a significant role in promoting the development of agricultural high quality, and the role of inland areas has a more significant effect. In the economic distance perspective, the digital financial inclusion index has a significant role in promoting the development of agricultural high quality. Under the perspective of economic distance, the positive spatial spillover effect of digital financial inclusion index on the level of high-quality agricultural development is obvious.

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 failure of Sci-Tech innovation financial market mechanism needs to be remedied by the government. By using AHP-DEA(analytic hierarchy process-data envelopment analysis) method, the government performance of Sci-Tech innovation financial in Hangzhou from 2007 to 2021 was analyzed. The results show that the government promotion efficiency of Sci-Tech innovation financial in Hangzhou is W-shaped, and the scale efficiency is relatively high. The promotion performance of the government has been increasing year by year, but stagnated from 2012 to 2013, mainly because the growth of input and output promoted by the government slows down or falls, and the efficiency was low. The government of Hangzhou should further increase the scale, optimize the structure, innovate the modes of input and increase the input and output of science and technology innovation to improve the performance.

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.

Grounded theory was used to analyze the influencing factors of Chinese medicine enterprises applying for FDA(Food and Drug Administration) certification in the United States, and a theoretical model was constructed to provide reference for Chinese medicine enterprises to make scientific strategic decisions. Interview data from strategic decision-makers of companies that have applied for and have not applied for US FDA certification was collected on CNKI, and then root code. After open coding, spindle coding, selection coding, and comparative verification, 28 open coding, 9 categories, and 5 main categories were finally sorted out, and a theoretical model was constructed based on the analysis of the logical relationship between each category. The strategic decision of traditional Chinese medicine enterprises to apply for FDA certification is based on a consistent understanding of FDA standards and the modernization and internationalization of traditional Chinese medicine. It not only aims to enter the European and American markets as a drug, but also promotes enterprise upgrading, enhances the modernization level of the traditional Chinese medicine industry, and achieves sustainable development during the application process.

Based on CiteSpace software, 765 core literatures on the topic of resource-based city transformation were visually analyzed. The results show that the transformation research of domestic resource-based cities has experienced three stages: less attention, rapid development and stable development, and more attention has been paid to the study of countermeasures and effect evaluation of resource-based cities. The scientific research cooperation in this field is weak, and the core authors and core institutions have not been formed. The research mainly focuses on three aspects: economic transformation and industrial structure, sustainable development and environmental protection, technological innovation and cultural industry. In the future, it is suggested to deepen the exploration of transformation paths, strengthen interdisciplinary research, and empower the transformation of resource-based cities with innovation.

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.
