Based on the background of Chinese modernization, this paper discusses the generation logic and era connotation of farmers' common prosperity in rural areas, analyzes the three stages of the realization process, constructs the corresponding evaluation system and sets the stage goals. Through quantitative analysis of the achievement and trend of the goal of common prosperity for farmers and rural areas in 31 provinces of China by 2025 and 2035, a two-stage practical path has been proposed. The research results indicate that, in terms of achievement, most regions have achieved a target achievement rate of 90% by 2025 and over 70% by 2035. Among them, the achievement of shared prosperity among farmers and rural areas is higher than that of overall prosperity, and the difference in shared prosperity is mainly reflected in the consumption gap between urban and rural residents. The short-term shortcomings of overall prosperity are concentrated in the spiritual life level, and the focus of medium and long-term improvement should shift to continuously empowering material life. From the perspective of implementation situation, the growth rate required to achieve the first stage goal is generally higher than that of the second stage, and it is expected that most regions in China can achieve the goal of common prosperity for farmers and rural areas by 2035 as scheduled.

Against the backdrop of negative population growth and persistently low fertility rates, exploring the current fertility situation and policies in China is of great significance for promoting long-term balanced and high-quality population development. The paper analyzes changes in China's fertility levels and demographic trends, pointing out key features of the current fertility rate in China, namely, the fertility rate is at an extremely low level, and is still declining, there are significant regional and urban-rural disparities in fertility levels, and the causes of low fertility are complex and diverse. It reviews the evolution and adjustment of China's fertility policy, and based on this, analyzes the framework of the current fertility policy. In this regard, it is proposed to improve the top-level design, enhance the synergy of policies, and build a fertility support policy system that covers the entire life cycle and the entire population. It is also suggested to clarify the main entities responsible for fertility and to reasonably share the costs of childbirth.

The results of the evaluation and spatiotemporal evolution analysis of local fiscal efficiency in China's Xinjiang from 2012 to 2021 show that there are significant regional differences in the comprehensive technical efficiency of fiscal expenditure among different regions in Xinjiang in the new era. In 2021, only 3 out of 14 regions in Xinjiang achieved DEA effectiveness in comprehensive technical efficiency of fiscal expenditure, while the rest of the regions showed DEA inefficiency and a clear trend of diminishing returns to scale. At the level of dynamic evolution, the total factor productivity of fiscal expenditure in various regions of Xinjiang shows a significant downward trend, and changes in comprehensive technological efficiency and technological progress are important reasons for the fluctuations. Over time, there is a possibility of local fiscal expenditure efficiency in Xinjiang shifting to the next neighboring region, but it is difficult to achieve a leapfrog transfer; At the spatial level, the number of regions that experienced efficiency leaps during the observation period was 10, while 4 regions maintained stable efficiency. Among them, the fiscal expenditure efficiency of various regions in the northern slope of the Tianshan Economic Belt had a strong regional driving effect, while the four southern Xinjiang prefectures showed a significant low-level spatial differentiation trend.

The construction of business environment is an important measure to implement the governance strategy of the Communist Party of China in the new era for Xinjiang, China. This paper, based on field research and text analysis, constructs an evaluation system for fiscal, tax, and financial preferential policies for enterprises from three aspects: policy synergy, completeness, and intensity and employs the grey correlation analysis to explore the impact of fiscal, tax, and financial preferential policies for enterprises on the construction of the business environment. The results indicate that Xinjiang's fiscal, tax, and financial preferential policies for enterprises have a high degree of synergy, and the degree of policy improvement and intensity are increasing in fluctuations. These policies can effectively promote the construction of local business environments. However, further improvement is needed in the diversification of policy tools and the implementation of preferential policies for enterprises. At the same time, it is necessary to deeply explore new models of fiscal, tax, and financial preferential policies that fully leverage the bilateral effects of policies and markets at special time points and events.

This paper empirically examines the impact of smart city construction on urban resource mismatch based on the panel data of 282 cities at prefecture level and above in China from 2009 to 2021, and on the basis of measuring the resource mismatch index of each city, using double-difference method, heterogeneity analysis and mediation effect analysis. It is found that, firstly, China's smart city construction can improve urban resource mismatch, and the results remain robust through the test. Secondly, mechanism analysis finds that China's smart city construction improves resource mismatch by reducing the level of government intervention and increasing the level of regional technological innovation. Thirdly, heterogeneity analysis finds that the mitigation effect of smart city construction on resource mismatch is most significant in the central region, and the improvement effect of smart city construction is not significant in the eastern and western regions. The mitigation effect of smart cities on resource-based cities is significantly better than that on non-resource-based cities. Therefore, under the new development paradigm, it is essential to build smart cities in a location-specific manner, innovate in the development of smart cities, intervene in the market in a rational way, promote the flow of factors, and enhance the efficiency of resource allocation.

The paper takes the a-share listed companies in China from 2018 to 2022 to investigate the contagion effect of shared auditors on the importance of financial audit, and calls the enterprises with higher or lower importance level as connected companies, and the enterprises with shared auditors with the connected companies as connected companies. The study found that when the connected company is in the same industry as the connected company, companies with shared auditors with higher importance linked companies (linked companies), its importance level is also high compared to other companies (non-connected companies), that is, shared auditors have a contagion effect on the importance of financial audit under the high importance level. And when accounting firms are large, the positive correlation between the contagion effect of shared auditors on the importance level of financial audit is weakened. When the connected company is in the same industry as the connected company, shared auditors do not have a contagion effect at a low importance level. When the connected company and the connected company are not in the same industry, shared auditors do not have an infectious effect on the importance of financial audit.

With the deepening advancement of carbon peaking and carbon neutrality goals, ESG Rating has gradually become an important criterion for measuring the sustainable development ability of enterprises. If enterprises can improve their ESG performance, not only can they enhance their social image and brand value, but they are also expected to achieve long-term sustainable development and high-quality economic and social development by optimizing tax strategies. Taking SynTao Green Finance's first announcement of corporate ESG Rating as an exogenous shock event, based on data from A-share listed companies from 2010 to 2022, a multi time difference in differences model was constructed to empirically explore the impact of ESG Rating on corporate tax avoidance behavior and its transmission mechanism. The study found that ESG Rating can significantly reduce corporate tax avoidance. The mechanism test shows that ESG Rating inhibit corporate tax avoidance by easing financing constraints, improving information transparency, and increasing government subsidies. Heterogeneity analysis shows that ESG Rating have a more significant inhibitory effect on corporate tax avoidance behavior among non-state-owned enterprises, enterprises with low shareholding ratios of institutional investors, and enterprises with low tax collection and management intensity. In the future, it is of great necessity to innovate the market soft supervision mechanism, strengthen external supervision and tax management, guide enterprises to improve their ESG performance, and promote their compliance with tax regulations.
