General purpose technologies (GPTs) exhibit strong externalities and innovational complementarities. Their diffusion within supply chains and impact on the technology ecosystem are of significant interest to both industry and academia. Based on the resource dependence theory and absorptive capacity theory, the nonlinear effects of leader firms' GPT innovation on the technological complementarity between leader firm and its supply chain partners was examined. It also explores the boundary conditions of these effects. Analyzing panel data from 1,405 firm-year observations of 145 biopharmaceutical firms from 2010 to 2019, the findings reveal that an inverted U-shaped effect of GPT innovation performance on the technological complementarity between leader firm and its supply chain partners.Within the supply chain, partners' capability in GPT innovation positively moderates this inverted U-shaped relationship.

Based on the resource-based view and dynamic capability theory, using large sample survey data from high-tech manufacturing enterprises, the mechanism and boundary conditions of the impact of digital orientation on new product development(NPD) performance was empirically analyzed. The results show that digital orientation has a positive impact on NPD performance.Organizational agility partially mediates the relationship between digital orientation and NPD performance.Top management team heterogeneity not only enhances the positive impact of digital orientation on organizational agility, but also strengthens the mediating path of organizational agility between digital orientation and NPD performance, that is, top management team heterogeneity plays a moderated mediating role. The research conclusion can provide theoretical and practical guidance for enterprises to effectively improve NPD performance under the drive of digitalization.

After field application in Linxing Area, the productivity of volumetric fracturing is increased by 1.3 times compared with that of conventional fracturing. With exceptionally abundant tight sandstone gas reserves in Linxing, the friability evaluation-guided volume fracturing technology represents a significant innovation in hydrocarbon development. This approach has shown growing advantages in unconventional resource exploitation and holds broad prospects for industrial applications.

Based on the qualitative research methodology of rootedness theory, 71 typical cases of rural governance were selected as the research basis, and the “subject-institution-technology-industry” practice framework for effective rural governance was extracted. It is found that grassroots organizations have positively driven the construction of rural revitalization by stimulating the vitality of the main body, establishing a sound system, introducing advanced technology and promoting industrial development. The realization of the overall goal of rural revitalization will be influenced by different subjective and objective factors, which will form the process of “reverse shaping” for the realization of effective rural governance in localities. In the practice of rural governance, the “top-down coordination” among multiple governance subjects and the “complementary coordination” among different institutional forms serve as internal driving forces, effectively empowering the implementation of the rural revitalization strategy. The “matching of supply and demand” of talents and technology, and the “internal and external” of the collective economy and social capital, as effective external driving forces for rural governance, have strongly contributed to the realization of rural revitalization.

In recent years, high-tech enterprises have shown good performance in innovation output. Using a total of 5 418 sample data from 2021 to 2023, a regression model for empirical analysis was established to explore the impact of R&D expenses and R&D personnel on the innovation performance of enterprises. The research results show that both R&D expenses and R&D personnel have a positive impact on the innovation performance of enterprises. Heterogeneity analysis reveals that R&D expenses positively promote the innovation performance of large, medium, and small enterprises, but have no significant impact on the innovation performance of micro enterprises.

Methods such as literature review, logical analysis, and SWOT (strengths, weaknesses, opportunities, threats) analysis were used to conduct a systematic examination of the development of sports tourism in Guiping City, aiming to explore its strengths and weaknesses while proposing feasible countermeasures. Through SWOT analysis, it is found that Guiping's advantages including strategic transportation positioning, abundant tourism resources, and rich historical heritage. However, challenges persist in inadequate understanding of sports tourism and insufficient market development expertise. Opportunities arise from contemporary demands for integrated development, supportive policies, and digital-intelligent empowerment, while threats include ecological-environmental conflicts and homogeneous competition from neighboring cities. Development strategies for Guiping's sports tourism are proposed, including the rational integration and development of sports tourism resources, adopting a “sports + tourism” oriented approach citywide, cultivating interdisciplinary management professionals, creating an eco-sports tourism brand with local characteristics, and enhancing governmental support and policy reinforcement.

Static pressure densification piles exhibit significant technical and economic advantages in addressing the collapsibility of loess. However, during construction, there is a widespread issue of severe shrinkage after static pressure hole formation. To address this, specialized field tests were conducted using the volume conversion method to compare and analyze the shrinkage conditions of static pressure densification piles after the first and fourth hole formations. It is found that shrinkage occurred to varying degrees after both hole formations, with the overall shrinkage rate after the fourth hole formation reaching as high as 26.54%, an increase of 101.40% compared to the first hole formation. To effectively tackle this challenge and ensure the quality of pile construction, the importance of the tamping and filling process stands out. Given the limitations of traditional heavy hammer tamping methods in terms of construction efficiency, quality control, and environmental protection, an innovative fill-tamp integrated device has been developed. This device not only improves the quality and efficiency of densification pile construction but also advances tamping and filling technology, achieving dual improvements in economic and social benefits, and it has value for promotion and application.

For the convenience of installation, the bolt hole diameter in the transmission tower is generally required to be 1.5 mm larger than the diameter of the bolt, and there is sliding phenomenon after the bolt is subjected to force. The current tower design software generally uses a spatial truss model for analysis, without considering the influence of bolt slip, which cannot accurately reflect the actual deformation of transmission towers. As a result, the calculated deformation values are generally much lower than the measured values, which affects the accuracy and safety of structural internal force analysis. At present, the analysis of the impact of bolt slip on deformation is mainly carried out through finite element software combined with spring elements. Due to the large number of transmission tower members and complex structure, this processing method has low efficiency and is generally only used for verification analysis of tests. Based on the principle of virtual work, considering bolt slip and residual deformation, the calculation formula for tower deformation is improved, and fast identification methods for various joint models are proposed. At the same time, a full-scale real type experimental study was conducted for the deformation of the yak shaped landscape tower for the first time, and the experimental results, theoretical calculation values, and improved formula calculation values were compared and analyzed to verify the effectiveness of the improved formula. In addition, the measures to reduce bolt slip deformation are proposed. The research results have certain reference value for the optimization design of transmission tower, deformation control, and evaluation of bearing capacity under foundation deformation conditions such as landslides and settlements.

In recent years, the rapid development of digital new quality productivity has given rise to the smart transportation industry chain. Taking the resilience of the smart transportation industry chain as the research object, its resilience connotation and influencing factors were defined. The OSM(objective-strategy-measurement) model was employed to construct a diagnostic index system for industry chain resilience from three dimensions: resistance, transformation, and recovery capabilities. “G1+CRITIC”(order relation+CRITeria importance through intercriteria correlation) information entropy diagnostic model was proposed for diagnosing industry chain resilience. Data from 2015 to 2024 of Jiangsu Province was selected for empirical analysis. The results indicate that the level of resilience in the smart transportation industry chain mainly depends on the recovery capability of the industry chain. The diagnostic model can effectively evaluate the resilience level of the industry chain and identify weaknesses. Based on the diagnostic results, precise measures to solidify and strengthen the industry chain can be proposed.
