The coordinated development of rural infrastructure and ecological environment is an effective way to improve agricultural productivity. The primary focus of the current research is how the two can work together to promote regional economic development in rural areas and in related fields. This study takes the western region as the research object, constructs an evaluation index system for rural infrastructure and ecological environment, and uses the Min-max Scaling method, coupling coordination model, gray GM (1, 1) model, and standard deviation elliptical model for evaluation. The trends and driving factors for the coordinated development of rural infrastructure and ecological coupling in the region from 2012 to 2021 are analyzed. The main results are as follows: (1) Except for Tibet, Qinghai, and Ningxia, the coupling degree of rural infrastructure and the ecological environment in western China reached the maximum level during the research period, also the coordination degree showed a gradual upward trend. (2) A prediction for the development and evolution of rural infrastructure and the ecological environment in western China indicates a trend of agglomerative development in the southern region. (3) By strengthening the construction of reservoirs, improving sanitary conditions, improving cultivated land use area and forest coverage, and controlling soil erosion, the coordinated development of the two can be effectively promoted. The purpose of this study is to promote the sustainable and coordinated development of rural infrastructure and ecological environment, and to provide a reference for policy formulation in the relevant sectors and other countries and regions with similar situations.

Abstract: The distribution of energy and industry in China is extremely uneven. The western region is rich in energy resources but relatively economically backward, while the eastern region, particularly, the southeast coastal area, is an industrially-developed area but is short of energy resources. On the basis of such a situation, this paper recommends the sustainable development of energy systems for the western region. The specific innovative energy systems adopted here can convert the western region''s fossil fuels to alternative fuels and electricity with higher efficiency, lower investment cost, and less impact upon the environment. As one of such innovative energy systems, the MES (multi-functional energy system) can achieve 10–14% in the energy conservation ratio, 4–8% reduction of investment cost, and a 10–37% decrease of main pollutants. Moreover, its adoption will increase the income and accelerate the development of the energy industry in the western region, as well as meet the energy demand of the eastern region. The analysis in this paper presents a feasible energy road map for the rapid yet sustainable development of China''s western region. [Copyright &y& Elsevier]

• We analysed the influencing factors of urban eco-efficiency in Western China. • The US-SBM model and spatial econometric models were used for 84 cities' data. • Urban eco-efficiency showed a fluctuating upward trend during 2004–2017. • Economic development and urbanization had U-shaped impact on urban eco-efficiency. • Four explanatory variables showed a positive impact on urban eco-efficiency. Improving eco-efficiency can promote sustainable development. This study first evaluated the urban eco-efficiency of 84 cities in Western China from 2004 to 2017 by the undesirable-super-slack-based measure (US-SBM) and analysed their spatiotemporal characteristics, and then investigated its influencing factors using spatial econometric models. The results indicated that the urban eco-efficiency in Western China was at a relatively low level and showed a fluctuating upward trend with the highest average value of 0.65; however, capital cities of Western China have improved their eco-efficiency rapidly. Furthermore, there were obvious spatial spill-over impacts of the urban eco-efficiency in Western China. This paper also found that both the economic development level and urbanization level have "U" shaped impacts on Western China's urban eco-efficiency, which decreases at first and then rises. Similarly, increasing the proportion of secondary industry promotes urban eco-efficiency, and FDI, trade activities, improved environmental regulations as well as technological innovation capabilities have a positive impact on urban eco-efficiency in Western China. This paper also put forward corresponding policy suggestions to promote Western China's urban eco-efficiency. The present study may be helpful for policy-makers to balance economic development and environmental protection in Western China. [ABSTRACT FROM AUTHOR]

To realize sustainable development, China has vowed to build the circular economy for many years, but the level of development of this economy differs significantly in various regions of China. This study aims to examine the factors influencing residents' willingness to participate in the circular economy in Western China. We collected 791 online questionnaires from residents living in western Sichuan Province and Chongqing City. Based on the survey data, the Theory of Planned Behavior is adapted to construct a structural equation model. The empirical results indicate that four variables (i.e., Subjective Norm, Willingness to Sacrifice for the Environment, Perceived Economic Benefit, and Positive Anticipated Emotion) have significant effects on residents' willingness to participate in the circular economy. In addition, there is also evidence for Green Purchase Intention as a mediator for the relationship of Willingness to participate in circular economy with Subjective Norm, Willingness to Sacrifice for the Environment and Perceived Economic Benefit, and evidence for Perceived Behavior Control as a moderator of the relationship between Willingness to participate in circular economy and Positive Anticipated Emotion.
