Financial S&T expenditure is very important for promoting national S&T innovation and high-quality development. Firstly, the LP method was applied to measure the total factor productivity of enterprises and the economic transformation ability of fiscal S&T expenditures in Xi’an city was discussed. Secondly, taking the Xi’an listed companies in Shanghai and Shenzhen from 2012 to 2022 as samples, an empirical research on how fiscal S&T expenditures affect the TFP of enterprises was conducted through the method of matching with macro data. The results show that increasing the intensity of fiscal S&T expenditures helps to improve enterprise total economic productivity. In view of this, in order to improve the total industrial productivity of enterprises in Xi’an and to play the role of leverage of fiscal S&T inputs on economic development, not only the input-output structure of fiscal S&T expenditures should be considered, but also relevant suggestions should be put forward from the government’s point of view.

Since 2021, China has opened its three-child policy, and the relevant supporting measures to support fertility have been continuously improved at the national and local levels. However, the number of newborns and the birth rate have not met expectations. Based on the 2021 China General Social Survey (CGSS) data, the unordered multiple classification Logistic regression model was used to explore the impact of the number of children on the labor force participation of reproductive women.The results show that the increase in the number of children will reduce the participation level of reproductive women in non-agricultural labor and increase the probability of non-participation in work. In addition, women’s age, education level, spouse’s labor participation status, spouse’s annual income, family residence, whether they live with their spouse, and family annual income all affect the labor participation status of women of childbearing age.

To promote urban-rural integration and establish an internal circulation channel between urban and rural areas, it is necessary to facilitate the flow, interaction and balanced allocation of the four dimensions of people, land, industry and governance. Taking Longweiba Village in Zhangjiajie City, Hunan Province as a case study, the symbiosis theory from ecology to analyze the synergistic dynamic evolution process of “people-land-industry-governance” in rural areas was employed. Based on the framework of “symbiotic unit-symbiotic environment-symbiotic mode” derived from symbiosis theory, a synergistic development path for rural areas was proposed, in order to activate the vitality of rural population, land, industry, governance and other elements, achieve new endogenous rural development, and provide referential experiences and suggestions for other rural areas.

Cultural and creative industry is not only a new engine of economic growth, but also an important driving force for cultural and social development. Based on the modified spatial gravity model and social network analysis method, combined with the relevant data from 2000 to 2019, the spatial correlation and network structure evolution characteristics of China’s cultural and creative industries were studied and analyzed. The results show that the scale of China’s cultural and creative industries continues to expand, and the spatial correlation intensity increases year by year, and always presents an extreme distribution pattern of “strong in the east and weak in the west”. The core-periphery structure of China’s cultural and creative industries is obvious, with the core area more concentrated in the eastern coastal area and the fringe area mainly distributed in the western area of China. China’s cultural and creative industries have become more and more closely connected, forming a cohesive subgroup with close internal relations. The internal connections of subgroups are relatively stable, but the overall connections still have great shortcomings. There are different spillover relationships among the “main beneficiary”, “two-way spillover” and “broker” subgroups, and they play an important role in the whole network.

In order to effectively enhance the service quality of airports, the optimal scaling method was employed to conduct a spatio-temporal characteristic analysis of the airport passenger complaint data from the official website of the Civil Aviation Administration of China from 2010 to 2018. The following conclusions are as follows. Regarding temporal characteristics, passengers pay more attention to comfortance during the transportation off-season, punctuality during the transportation peak season, and convenience during the transportation low season. Regarding spatial characteristics, the complaint themes in East China and Central-South China regions are more inclined towards comfort, those in Southwest and North China regions are more inclined towards punctuality, those in Northwest and Northeast regions are more inclined towards convenience, and those in Xinjiang region are more concerned about safety. Countermeasure suggestions are provided to tailor measures to suit local conditions to the specific time and manage the whole process of the dealing about complaints.
