Under the “dual carbon” target, the topic of corporate ESG information disclosure has become a hot research topic nationwide. As China is still in the initial stages of sustainable disclosure, most research solely concentrates on the rating of ESG information, overlooking the quality of ESG information disclosure. Therefore, from the perspective of sustainable disclosure standards for enterprises, taking the construction machinery industry as the research sample, a fuzzy comprehensive evaluation model was adopted to establish a quality evaluation system for enterprise ESG information disclosure, in order to assist the subsequent application of sustainable disclosure standards for enterprises and further standardize ESG information disclosure work in China’s industry.

Traditional research on crew scheduling problem is difficult to directly measure the real fatigue of crew when working. Crew fatigue is affected by a variety of real-world factors. A quantitative model of crew fatigue was established to measure the fatigue of the crew’s task loop, and a crew scheduling model was further constructed. Then an algorithm was designed to solve the model based on the column generation framework combined with the dynamic constraint aggregation method. Finally, numerical experiments demonstrate that the algorithm is able to solve the larger-scale crew scheduling problem in a shorter time, and the model established in this paper is able to effectively reduce crew fatigue.

Air freight is an important part of modern transportation logistics system. In recent years, with the continuous development of air freight industry, the freight volume has continued to grow. Therefore, accurate prediction of air freight volume is very important for the development and operation of air transport industry. In order to scientifically predict the air cargo business volume between cities and comprehensively consider the influencing factors such as the level of urban economic development and airport facilities, the grey forecasting model was used to predict the total cargo business volume of airports, and then the comprehensive service capacity score of urban airports and the freight attraction intensity between urban nodes were determined by using principal component analysis and improved gravity model, so as to judge the trend of cargo flow. Finally, the freight volume between urban airports in 2026 was obtained by constructing a combined forecasting model. The results show that China’s air freight business market is in a period of rapid development, and the forecast of freight volume has certain reference value for setting the operating capacity of freight airports and improving the support capacity of logistics facilities.

Digital transformation is an important way to enhance enterprise resilience. Taking Shanghai and Shenzhen A-share listed companies as the research object, the data from 2011 to 2021 were selected, and the research findings were found by empirical test. Enterprises’ digital transformation can significantly improve enterprise resilience, and this conclusion is still valid after a variety of robustness and endogenous tests. Among them, innovation efficiency and innovation quality play a part of intermediary role in the impact. In order to better enhance the resilience of enterprises and enable enterprises to achieve sustainable development, enterprises should further strengthen digital construction and attach importance to the improvement of innovation ability.

In the digital economy era, online markets are crucial venues for resource allocation, and optimizing resource allocation is a vital pathway to promote industrial transformation and upgrading. Based a two-way fixed effects model, a mediation effect model and a threshold effect model, the impact and underlying mechanisms of the development of online markets on the optimization of industrial structure in China were analyzed, using data from 288 prefecture-level cities from 2014 to 2021.It is found that the development of online markets significantly enhances the advancement of industrial structure but somewhat inhibits the rationalization of industrial structure. These conclusions remain robust after a series of robustness checks. The mediation effect test results show that the development of online markets can promote the advancement of industrial structure by improving resource allocation efficiency. Further analysis indicates that the promotion of industrial structure advancement by online markets exhibits heterogeneity, being more significant in the eastern and western regions, in areas with larger populations, and in regions with lower levels of digital infrastructure. The threshold model results reveal a marginally increasing nonlinear characteristic in the promotion of industrial structure advancement by the development of online markets. Therefore, to fully leverage the resource allocation role of online markets, it is necessary to further expand the scale of online markets, regulate their operations, define the boundaries of different types of online markets, strengthen market access reviews, enhance the role of data mechanisms, and bolster anti-monopoly and market supervision to encourage more participants. Different regions should be encouraged to adopt differentiated strategies for online market development.

Marine tourism is a characteristic brand of Guangdong tourism,as well as one of the pillar industries of Marine economy in Guangdong Province. Based on the research of industry chain, the relevant standards of the Classification of Marine and Related Industries (GB/T20794—2021) and the Statistical Classification of National Tourism and Related Industries (2018) were combined, the Marine tourism industry chain was sorted out, the marine tourism industry chain and various industry segments in Guangdong Province synchronously were analyzed. The results show that the marine tourism industry chain in Guangdong is relatively complete, all aspects are involved. There are still insufficient in the cultivation of marine tourism formats, weaknesses in the manufacturing of facilities and equipment, and imperfections in training and leasing of marine tourism services in Guangdong’s marine tourism industry chain at present.
