With the development of information technology, data has become a valuable asset. Conducting a comprehensive and objective evaluation of the value of data assets has become a current research hotspot. Taking Internet enterprises as the research object, after comparing data asset evaluation methods, the multi-period excess earnings model was selected to evaluate the value of data assets of Internet enterprises. Due to the deficiencies of the traditional model such as unclear contribution amount and difficult determination of the income period, ANP (analytic network process) was introduced for secondary differential division to effectively subdivide the income contribution amount of data assets. The Pearl curve was used to determine the income period. An improved multi-period excess earnings method-based data asset value evaluation model for Internet enterprises is proposed. The research results show that the improved model can effectively solve the problem of inaccurate evaluation and provide methodological support for the asset value evaluation of Internet enterprises.

Enterprise resilience is one of the important capabilities of enterprises to respond to external crises, and how to improve corporate resilience and promote the steady and healthy development of the economy has become an important issue worthy of attention. Based on this, the A-share listed companies in Shanghai and Shenzhen from 2013 to 2022 was taken as a research sample to empirically test the impact of the asset-light operation model on the resilience of enterprises, and the impact of property rights on the relationship between the two. The empirical results show that the asset-light operation model positively affects the resilience of enterprises, and the property rights will weaken the positive correlation between the two.

Taking the green supply chain consisting of one manufacturer and one retailer as the research object, the effects of channel demand discount and the manufacturer’s social responsibility on the manufacturer’s channel choices under the equal retail pricing strategy and the three channel strategies were studied. The findings show that when the level of social responsibility and the discount coefficient of demand shifting are low, it is optimal for the manufacturer to open both retail and direct sales channels, and when the level of social responsibility and the discount coefficient of demand shifting are high, the manufacturer achieves the best total profit by retaining only the direct sales channel.

Promoting industrial ecologicalization is an inevitable choice for achieving sustainable development. Grounded theory was applied to analyze the ecological structure of the prefabricated construction industry, the mature ecological structure system of the industry was delved into. A four-dimensional industrial ecological structure framework of “resource environment ecological culture application execution management control” was constructed. The connotation of mature ecology in the prefabricated construction industry was defined. Comprehensive characterization of the mature ecological structure system of the prefabricated construction industry. By analyzing the case, an industrial ecological model was established and optimization strategies were provided to verify the accuracy of the system. Reference on how to achieve greater benefits in various aspects through ecological transformation in the prefabricated construction industry is proposed.

China has entered the era of digital economy, and the demand of enterprises for digital technology skills is increasingly prominent.In order to better meet this demand, the Chinese government has formulated a series of digital technology skills training policies. the PMC(policy modeling consistency) index model of digital technology talent training policy in Beijing, Tianjin and Hebei was established, and the model was used to conduct quantitative evaluation of related policies.It is found that the training policies of digital technical talents in Beijing, Tianjin and Hebei are qualified and can play a certain role in the training of digital technical talents. Compared with excellence, there is still a distance. Finally, some suggestions are put forward to optimize the policy of digital technical talents in the Beijing-Tianjin-Hebei region.

The widening of the gender income gap seriously hinders the realization of common wealth, while the development of the digital economy brings new solutions to effectively alleviate the gender income gap, realize common wealth and the high-quality development of China’s economy. The impact of digital economy development on the gender income gap was investigated by constructing an indicator system for measuring the digital economy in each province and combining the data from 2015 to 2021 China General Social Survey (CGSS). It is found that digital economic development can alleviate the gender income gap. The digital economy can significantly increase individual incomes in terms of different time years, age groups and skill differences, as well as mitigate gender income gaps. The quantile regression results show that the development of the digital economy raises the income of middle- and high-income women significantly more than that of men. Discrimination is still the main reason for the gender income gap. Expanding flexible employment channels for women, strengthening the protection of women’s rights and interests, utilizing the advantages of the Internet platform, and strengthening the training of women’s digital resources can increase women’s income and narrow the gender income gap.

Based on the extended gravity model, the impact of business facilitation in RCEP(Regional Comprehensive Economic Partnership) countries on China’s OFDI(outward foreign direct investment) was empirically examined, using China’s panel data on OFDI from 2005 to 2020.The results show that the facilitation of business environment in RCEP countries is conducive to promoting the growth of OFDI in China, but the results are different in each sub-indicator of business environment. The facilitation of the business environment in RCEP ASEAN countries has a promoting effect on China’s OFDI, while the promotion effect of RCEP non-ASEAN countries is not obvious. Based on different investment motives, the impact of business facilitation in RCEP countries on China’s OFDI is also different. With the in-depth implementation of RCEP, the business environment of various countries will continue to be optimized, and the level of China’s direct investment in RCEP partner countries will continue to rise.

Pre-application evaluation of patents is important to improve patent quality, form high-value patent, and promote the transformation of achievements. By investigating the current situation of pre-application evaluation of patent in domestic universities, the problems existing in the pre-application evaluation of patents in universities was analyze. A classification and grading pre-application evaluation model for patent is proposed, which is guided by improving the quality of patent applications and creating high-value patent, taking objective elements as evaluation indicators, and taking into account the classification and grading of different application purposes of the invention body in terms of school organization and personnel allocation, fund investment, and the differences in the application purposes of the invention body. Since different evaluation levels are adopted for different invention bodies, compared with traditional evaluation, it can effectively reduce personnel and capital investment.

Universities are important support for local economic use of scientific and technological innovation resources to form new quality of productivity.Analyzing the current situation of patent quality and conversion in universities is of great significance for improving the quality and conversion of patents in local universities. Taking universities in Anyang as the research object, a complete patent database of 7 universities in Anyang was formed through incoPat. Combined with the patent policies and regulations of Universities in Anyang, the quality and transformation status of patents were analyzed. It is found that the patent quality of universities in Anyang is not high, the effective patent implementation rate is extremely low, and the patent conversion situation is poor. The main reason is that there are obstacles in the system, operation, cooperation, and implementation of intellectual property management in universities. It is suggested to established and improve institutional mechanisms for industry university research cooperation, high-value patent cultivation, intellectual property talent cultivation, and intellectual property administrative management.

In order to better grasp the future development direction and innovative development path of transport aircraft and their propulsion systems, the first-principles analysis method was used to analyze the Breguet range equation. The results show that the innovation and development of transport aircraft mainly revolves around three dimensions, including the improvement of aerodynamic performance, the improvement of weight performance and the improvement of propulsion performance. The innovation and development of aircraft technology depends on the progress of aviation science and technology on the one hand, and is affected by the development environment on the other hand. The power is still based on the turbofan engine with large bypass ratio, and the use of new concept engines such as hybrid electric vehicles mainly depends on technological breakthroughs such as batteries.
