The recent wave of scientific and technological advancements, has resulted in the emergence of sophisticated digital products and premium digital service components. Furthermore, the enhancement of the quality of export products serves as a significant indicator of the high-quality development of China’s foreign trade. Utilizing data from A-share listed companies and corresponding data from the customs database spanning the years 2005 to 2015, the implications of the liberalization of digital service trade was examined. The findings suggest that the digital service trade substantially contributes to the improvement of export product quality among manufacturing firms. Furthermore, the influence of digital service trade liberalization on the quality of export products varies across different dimensions. The impact of export product quality enhancement is more pronounced in foreign-funded enterprises, capital-intensive industries, and particularly in the central and western regions of the country. Furthermore, larger enterprises located in these regions exhibit a more significant effect on product quality improvement. The mechanisms through which the openness of digital services trade influences the export product quality of manufacturing firms include enterprise productivity and the servicization of manufacturing processes.

Tourism gaze profoundly influences the perception of ancient town landscapes by both tourists and residents. Taking the photos and reviews of Qikou Ancient Town posted by tourists on Dianping website as data sources, combined with content analysis and social network analysis methods, NVivo11.0 and Gephi software was employed to investigate the perceptual characteristics of Qikou Ancient Town’s cultural landscapes from the perspective of tourism gaze. The results reveal that tourists primarily focus on cultural landscape elements such as the ancient town’s rivers, streets and traditional dwellings which perceive material cultural landscapes significantly more than non-material cultural landscapes. In terms of landscape combination perception, tourists have the highest perception of the combination of natural and material cultural landscapes, while their perception of non-material cultural landscape combinations is relatively low. Under the gaze of tourism, the perceptual interaction pattern between tourists and the ancient town landscape exhibits a deep integration of selectivity and interactivity. Moreover, residents’ perception of Qikou Ancient Town’s cultural landscapes has undergone significant changes, including a re-recognition of the value of the ancient town’s cultural landscapes and selective changes in cultural landscape perception based on tourist interest and economic value. In light of this, the study recommends balancing the display of material and non-material cultural heritage, enhancing the quality of the ancient town landscape, and promoting harmonious integration of the ancient town landscape to enhance the perceived experience and satisfaction of tourists and residents.

The ecologicalization of prefabricated building industry plays an important role in promoting the coordinated development of industrial entities and the diversified transformation of industrial value.

Finally, a case analysis was conducted on the innovation ecosystem of the prefabricated building industry in Changsha. The results show that the symbiotic effect coefficient between each subject reflects the degree of interdependence and the closeness of the cooperative relationship between different subjects. The mutualistic symbiotic evolution model can give full play to the synergy between subjects, and targeted policies are put forward for the symbiotic evolution of the system, providing a reference for the symbiotic development of the prefabricated building industry.

The core factors influencing production levels in manufacturing enterprises under the empowerment of the Industrial Internet and their mechanisms of action was investigated. Using grounded theory and the Analytic Hierarchy Process(AHP), key factors were systematically identified that enhance production levels in manufacturing enterprises empowered by the Industrial Internet. Supported by grounded theory, in-depth interviews and open coding were conducted to initially extract the main influencing factors. Subsequently, AHP was applied to perform a weight analysis on these factors, filtering out the most impactful ones. Finally, using a real case study, the mechanism was summarized by which the Industrial Internet empowers the enhancement of production levels in manufacturing enterprises. The results indicate that factors such as operational proficiency, equipment fault warning capability, and data cleansing efficiency significantly promote production levels in manufacturing enterprises under the empowerment of the Industrial Internet. These factors synergistically construct a systematic improvement mechanism. Based on the analysis results, targeted recommendations are provided, offering practical guidance for manufacturing enterprises to more effectively leverage Industrial Internet platforms to improve production levels.

The upgrading of export product quality propels the manufacturing industry to transition from a cost advantage to a quality advantage, facilitating the transformation of the trade model from quantity growth to a balance of quality and efficiency, and accelerating China’s progress towards becoming a trade power. The internal mechanism of service industry openness on the quality of manufacturing export products from the perspectives of the business environment and technological innovation was explored. Empirical analysis shows that for every 1% increase in the level of service industry openness, the quality of manufacturing export products improves by 0.373%, primarily attributed to the improvement of the business environment and technological innovation spillovers. Furthermore, the level of factor marketization also influences this relationship, exhibiting nonlinear characteristics. The enhancing effect of service industry openness on export product quality can only be fully exerted when the marketization of labor, capital and technological factors surpasses a certain threshold.

With the issuance of a series of supportive policies and the rapid development of emerging technologies, the digital public service system is continuously being improved and optimized. Focusing on the actual development of Shandong Province's digital public service system, an evaluation index system for digital public service quality satisfaction that includes 4 criterion layers and 15 target layers was established. Through questionnaire surveys, a fuzzy comprehensive evaluation model was employed to quantitatively assess the quality of digital public services in Shandong Province, and a thorough analysis of the existing issues, particularly the deficiencies in service quality and service innovation was conducted. Based on this, targeted improvement strategies are proposed such as enhancing the timeliness of problem resolution, improving information transparency, strengthening multi-department service integration, providing personalized services, promoting intelligentization levels, and optimizing service processes, in order to effectively enhance the quality of digital public services in Shandong Province and meet the growing service demands of the public.

Basing on the relevant indicator data of Fujian Province from 2008 to 2022, the comprehensive development level of cultural and tourism industries was measured. The coupling coordination model was used to explore the evolutionary characteristics of the coupling coordination degree between the two industries. The results show that the coupling and coordination status between the cultural industry and tourism industry in Fujian Province has entered a stage of high-quality coordination from severe imbalance, but it is still in the intermediate coordination stage at present. The obstacles are manifested as the lag of the tourism industry in the early times, afterward as the lag of the cultural industry, and now the lag of the tourism industry. In view of this, suggestions are proposed to establish a cooperation platform for cultural and tourism entities, and to utilize tourism projects for financing innovation, in order to promote the high-quality coupled development of the cultural and tourism industry.

In the construction of the Northeast Land Sea Corridor, it is an urgent need to enhance the driving force of Liaoning Province’s radiation belt towards the sea and land by leveraging the synergistic effect of the Liaoning Port Group. Taking six ports within the province as the research object, panel data from 2019 to 2022 were selected to evaluate the contribution of each port to the coordinated development of the port cluster using entropy weight method. The dynamic qualitive comparative analysis (QCA) method was used to find a feasible driving path to effectively promote the high level of coordinated development of the Liaoning port cluster. The results indicate that the level of coordinated development of ports is influenced by multiple conditional variables. There are three configuration paths that affect the level of coordinated development of ports, with potential substitution relationships between configurations and no significant time or individual effects found.
