New-type industrialization is accelerating,which puts forward higher requirements for the stability, scalability, security and intelligence of Internet basic resources. In order to improve the technological innovation capability of Internet basic resources such as domain names, IP addresses and AS numbers, innovation institutions in the field of Internet basic resources need to rely on national science and technology innovation projects to carry out major technological breakthroughs and improve platform service capabilities, they need to establish an independent innovation project system to accelerate technological innovation and cultivate scientific and technological talents. Therefore, the demand for innovation of Internet basic resources was analyzed. The construction path of hierarchical and classified independent innovation project system was introduced, a hierarchical layout system of independent innovation projects covered was built by six categories of projects, including strategic planning, policy theory, standard system, key technologies, system tools and platform solutions, and establishes a project approval mechanism that combines top-down and bottom-up approaches. It aims to build a system of independent innovation projects with reasonable layout, scientific management and comprehensive coverage, thus promoting self-reliance and self-improvement of scientific and technological innovation in the field of Internet basic resources, and helping to accelerate the promotion of new-type industrialization.

Using China’s listed manufacturing companies from 2011 to 2022 as research samples, whether government subsidies obtained by listed manufacturing companies affect the development of new quality productivity was empirically tested. The research results show that government subsidies can promote the manufacturing listed companies to improve the level of new quality productivity, and it is found that enterprise performance plays a certain intermediary role. The group test further distinguishes the property right nature and company size, and it is found that non-state-owned companies and small scale manufacturing listed companies can improve their new quality productivity more if they get government subsidies. This conclusion can provide some theoretical support for improving the level of new quality productivity of listed manufacturing companies, establishing a standardized government subsidy system, and reasonably determining government subsidy standards.

Under the technical support of geographic information system(GIS), the country park in Yannan Mountain Area of Urumqi was taken as the research object. Based on the field investigation, 10 key ecological sensitivity evaluation indexes were selected. By applying analytic hierarchy process (AHP) to determine the weight of each factor, the evaluation index system of ecological sensitivity of country parks was constructed. The results show that the ecological sensitivity of country parksis mainly highly sensitive, with an area of 173.30 hm², accounting for 31.64%. The remaining sensitive areas are 91.07 hm², 93.01 hm², 126.07 hm², and 64.30 hm², accounting for 16.63%, 16.98%, 23.02%, and 11.74%, respectively.

In the context of the digital economy and VUCA(volatility, uncertainty, complexity, ambiguity) era, digitally empowering operations management has become an important strategy for manufacturing enterprises to operate steadily and develop efficiently, but there is still insufficient research in academia on whether and how digital capabilities (DC) can improve enterprise operational performance (OP). Based on the theory of dynamic capabilities, questionnaire survey data from manufacturing enterprises in China was used to empirically analyze the influence mechanism and boundary conditions of DC on OP. The results indicate that DC (intelligence capability, connectivity capability and analysis capability) have a positive impact on OP, supply chain resilience (SCR) partially mediates the relationship between DC and OP. Strategic matching positively moderates the impact of connectivity capability and analytical capability on SCR, but has no significant moderating effect on the relationship between intelligence capability and SCR. These results can provide important practical implications for effectively promoting enterprise OP under the digital context.

As a crucial hydraulic engineering structure, the impermeability of a rockfill dam directly affects the safety of the project, environmental protection, and economic benefits. Different protective measures are taken for cofferdams under different conditions, so a detailed analysis based on specific conditions is necessary. Focusing on the transverse soil and rock revetment upstream of Phase I of the Yanzhou hub, the large-scale finite element software GeoStudio was used to conduct an in-depth analysis of its various anti-seepage structural forms, aiming to evaluate the effectiveness and seepage control effects of each anti-seepage scheme.The research findings indicate that both the absence of anti-seepage measures and the sole use of geomembrane structures fail to meet the engineering requirements for seepage prevention. Although a single anti-seepage wall structure can meet the requirements, it is not the best choice due to its high construction difficulty and economic cost. In contrast, the anti-seepage solution combining high-pressure jet grouting with composite geomembrane can effectively fulfill the project’s seepage prevention needs, which provides practical guidance and suggestions for the design of earth-rock cofferdam.

Affected by the complex situation at home and abroad, the financing cost of Chinese enterprises is high. The VAT policy is one of the key measures to reduce taxes and fees, which has a significant effect on reducing the burden on enterprises. A differentially differential model was used to explore the impact of this policy on corporate debt financing costs based on pilot data from some industries in 2018. The results show that after the implementation of the policy, the debt financing cost of enterprises has decreased significantly, especially in the non-state-owned, small and competitive industries of enterprises, while the impact on state-owned and large enterprises is small. This result can provide a basis for further deepening the tax rebate policy and helps promote the healthy and sustainable development of enterprises.

The fault fracturezone has a significant impact on the progress and safety of tunnel construction, and it is necessary to determine the specific location and lithology information of the fault zone before construction. In order to ensure the smooth excavation and excavation of tunnels in the project, a combination of drilling and coring, natural source surface wave method, and comprehensive logging exploration methods were used to explore the specific characteristics of fault zones under complex geological conditions, and to conduct experimental analysis on their rock properties. The results indicate that under large-scale detection conditions, the natural source surface wave method can comprehensively survey the approximate characteristics of fault zones, and preliminary fault localization can be carried out based on the characteristics of wave velocity changes.The comprehensive logging method accurately identifies the specific location and distribution of faults based on parameters such as resistivity and natural potential, and provides quantitative analysis of the position, width, attitude, composition, cementation degree, and water content of fault zones. The combination of multiple methods improves the accuracy of fault fracture zone detection.
