The results demonstrated that the gap between Chinese residents’ dietary structure and the CDG predominantly manifests as a severe deficiency in dairy consumption. The nutrients currently recommended in the CDG cannot meet the needs of the human body and have significant environmental impacts. In terms of cost, rural residents’ incomes may not be sufficient to fully adhere to CDG recommendations.

This study aims to systematically delineate the application characteristics and trends of Social Network Analysis (SNA) in rural community research. Using a twofold approach, we integrate a traditional literature review and CiteSpace bibliometric analysis to assess the application status and evolutionary trends of SNA methods in this context. The key findings include the following: ① Chinese research trends: scholars predominantly concentrate on the “three rural” issues (related to agriculture, rural areas, and small-scale farmers) and social support mechanisms for vulnerable rural populations. With policy shifts, rural revitalization, tourism, governance, social trust, and multi-dimensional poverty are poised to emerge as hot topics for the future. For further refinement, we suggest that the application of SNA in rural community research could benefit from content expansion, long-term studies, and innovative modelling techniques. ② Research by international scholars has been primarily directed toward the physical and mental health of rural residents, as well as socioeconomic issues. Despite these studies covering a range of typical cases across various nations, a conspicuous lack of thorough, systematic, and prolonged efforts focused on rural community development in specific regions remains. Additionally, health issues affecting rural residents are expected to sustain long-standing and focused international academic attention.

Following the principles of relevance, scientific rigor, universality, reliability, and timeliness, this study constructs an assessment index system for sustainable development, covering seven themes corresponding to the UN Sustainable Development Goal 11. Through detailed calculations, we obtained sustainable development indices for 139 Chinese cities from 2016 to 2022 and analyzed them in three dimensions: distribution dynamics, regional differences, and convergence. The key findings are as follows. First, the level of sustainable development showed improvement, with the average score of included cities increasing by 11.88% from 2016 to 2022. Second, the level of sustainable development was relatively balanced, maintaining low Gini coefficients between 0.05 and 0.06. Third, a weak overall σ convergence feature existed, with increased differentiation in 2021. From a regional perspective, a σ convergence feature was observed in the northeastern but not in the western region. Fourth, both overall absolute <em>β</em>-convergence and conditional <em>β</em> effects were significant. Regional absolute <em>β</em>-convergence and conditional <em>β</em>-convergence were also significant.

As the global community intensifies its efforts to implement the sustainable development goals (SDGs), the demand for assessing progress in urban sustainable development has increased. This has led to the emergence of numerous indicator systems with varying scales and themes published by different entities. Cities participating in these evaluations often encounter difficulties in matching indicators or the absence of certain indicators. In this context, urban decision-makers and planners urgently need to identify substitute indicators that can express the semantic meaning of the original indicators and consider the availability of indicators for participating cities. Hence, this study explores the relationships of substitution between indicators and constructs a collection of substitute indicators to serve as a reference for sustainable urban development assessment. Specifically, building on a review of international and Chinese indicators related to urban sustainability assessment, this study employs natural semantic analysis methods based on the Word2Vec model and cosine similarity algorithm to calculate the similarity between indicators related to sustainable urban development. The results show that the Skip-gram algorithm with a word vector dimensionality of 600 has the best performance in terms of calculating the similarity between sustainable urban development assessment indicators.

Specifically, a “profit-reputation” utility function is proposed to reflect participants’ expectations regarding cooperation profit and sustainable reputation. Additionally, an Edgeworth box model is developed to describe the participant’s balance determinations as a contract curve, revealing the Pareto conditions for mutually beneficial transactions based on sustainable performance. Furthermore, several principal-agent models are established to analyze the equilibrium of sustainable transactions within the EV-LIB supply-chain under varying dominance scenarios. A case study of an EV-LIB transaction is conducted to demonstrate the feasibility and effectiveness.

Using a step-by-step “eliminate–replace–augment” indicator selection method that takes mature indicators from existing standards for city evaluation, we form an ILCSD that responds to the SDGs while meeting China’s specific needs. Using the ILCSD, cities can select a set of indicators to assess and monitor their strengths and weaknesses. Through empirical analysis, we verify the feasibility of using ILCSD to construct a CSD evaluation system for Beijing, China. For the first time, ILCSD has established a mapping relationship between the core indicators from domestic and foreign standards of city development and the SDGs . It provides a tool for cities in different regions, at different stages of development and with different endowment types to select high-quality indicators according to local conditions, effectively solving the “last mile” problem of SDGs implementation at the city level. In the process of implementing indicators, we further suggest that important indicators with incomplete statistical data should nevertheless be included in the scope of cities’ statistical monitoring.

The Zone also plays critical roles in addressing the developmental bottlenecks that China faces and sharing Chinese insights into global sustainable development efforts. On July 15, 2022, the State Council endorsed the Zone’s establishment in Zaozhuang City, Shandong Province, where it focuses on innovation-led sustainable development in rural areas. Research into the levels, impediments, interdependencies, and evolutionary trends of rural sustainable development is crucial. Therefore, this research aimed to assist in comprehensively assessing developmental challenges and facilitating the harmonious advancement of social, economic, and environmental aspects in rural areas. In pursuit of the three fundamental dimensions of the UN’s Sustainable Development Goals (SDGs), namely development’s drivers, quality, and equity, this study was grounded in China’s national Rural Revitalization Strategy and the demands of sustainable development strategies. It also aligns with the UN 2030 Agenda for Sustainable Development and the associated SDG indicators. Focusing on four key areas, namely production elements, natural elements, social elements, and rural governance, this study developed an evaluation index system for assessing the level of rural sustainable development. It employed a range of analytical models, including the game theory-based combination empowerment method, barrier degree model, coupling degree model, coupling coordination degree model, and gray prediction GM(1,1) model, to analyze the status and evolving trends of rural sustainable development in Zaozhuang City from 2015 to 2022.
