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.

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.

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.

In order to strengthen and toughen the functional refractory, carbon fibres were introduced as reinforcement in aluminium-carbon refractories in a new way using direct dispersion of the binding agent. The effects of different carbon fiber contents on the properties of aluminum-carbon refractories were studied. The changes of bulk density, apparent porosity, flexural strength at room temperature, compressive strength, thermal shock resistance and high-temperature flexural strength of the samples after high temperature treatment were compared and analyzed. Changes in the physical phase and morphology of the samples at different heat treatment temperatures were analyzed. The results show that after heat treatment at 1 100 ℃, the flexural strength at room temperature, compressive strength, residual flexural strength and high temperature flexural strength of the samples with carbon fiber were effectively improved compared with those without carbon fiber. Among them, the performance is optimal when the carbon fiber content is 0.1%. Well-developed silicon carbide whiskers were obtained from the carbon fiber samples heat-treated at 1 500 ℃ and bridged carbon fibres with the matrix as observed by SEM. This suggests that suitable carbon fibre-doped can make the sample obtain excellent high-temperature service performance will Under the dual reinforcement of carbon fiber and silicon carbide whiskers.

Based on China’s provincial panel data from 2012 to 2022, a provincial-level science and technology finance index system was established and an in-depth analysis of the influence mechanism of science and technology finance on the development of new-quality productive forces was conducted using two-way fixed effects model. The results show that science and technology finance has a significant promoting effect on the development of new-quality productive forces.The improvement of education levels and informatization levels can enhance the effect. Science and technology finance promotes the development of new-quality productive forces by increasing foreign investment and facilitating industrial structure upgrading. Science and technology finance exhibits heterogeneity in its impact on the development of new-quality productive forces in terms of regions, industrial structures, and degrees of openness.

In order to further explore the feasibility of key technologies, related products, markets, and policy measures in the hydrogen energy industry at different time nodes, an analysis framework for the development of the hydrogen energy industry was constructed based on industrial technology road-map. The incoPat patent database was used to clarify the current development status of the hydrogen energy industry through technology patent retrieval and analysis. Adopting questionnaire survey and expert interview afterwards,the development trend of China’s hydrogen energy industry is predicted and depicted from aspects of industrial environment, main products, key technologies, etc. Based on above predictions and depictions,a roadmap for the development of China’s hydrogen energy industry is drawn. In combination with the construction practice of Changping “Energy Valley”, suggestions for industrial development are systematically put forward, such as increasing technological research and development in the field of hydrogen production using renewable energy, actively promoting pilot demonstrations, accelerating the construction of a national hydrogen energy supply system and a whole industry chain system of hydrogen industry with green hydrogen as the core, improving the standard system, and strengthening international cooperation.

Digital inclusive finance is an important way to promote high-quality economic development and achieve consumption expansion and upgrading. It is found that digital inclusive finance can significantly improve the consumption level of households in China and the western region by using CHFS (China Household Finance Survey) micro household data, and digital inclusive finance can help household consumption through the intermediary mechanism of improving household income and regional digitalization. In order to make digital inclusive finance better realize the expansion and upgrading of consumption, on the one hand, it is necessary to increase policy support and promote the construction of digital infrastructure; On the other hand, it is necessary to improve the consumption and financial consumption concepts of households.

Tanhuasi Park was selected as the case area to collect photos and sounds, and the proportion of each element was identified by image semantic segmentation. Then, according to the saliency and universality of the sound, the sound of birdsong, the sound of water flowing, the sound of wind, and the sound of communication were selected, and the sound and picture were edited by Adobe Premierepro, and the questionnaire was filled in to calculate the recovery value of different sounds. The correlation analysis between landscape elements and sound was carried out, and it was concluded that birdsong had a significant positive correlation with tree and shrub coverage and plant species, water flow sound had a significant positive correlation with water quality and waterscape coverage, and communication sound was negatively correlated with the richness of landscape sketches. Based on this, strategies for improving the green space environment of urban parks are proposed.
