The concept of high-quality development (HQD) is characterized by its emphasis on efficiency, equity, and environmental sustainability. In the context of China’s new urbanization development, the metropolitan area plays a crucial role in facilitating and sustaining HQD. This study focuses on the Changchun Metropolitan Area (CCMA) as a case study to measure the efficiency of high-quality development (HQDE) at the county level using the super-efficiency SBM model and spatial autocorrelation model. Additionally, we examine the spatio-temporal distribution characteristics of HQDE in terms of economy, innovation, coordination, greenness, openness, and sharing (EICGOS). The main findings are as follows: (1) The HQDE of the CCMA ranges from 0.7 to 0.8 with an initial rapid increase followed by a gradual decline; however, there are notable variations among different counties. (2) Regarding spatial structure within the metropolitan area, highest efficiency is observed in the half-hour living circle followed by the 2-h accessibility circle while lowest efficiency is found in the 1-h commuting circle. Over time, there is a declining trend in efficiency within core leading areas. (3) In terms of dimensions, CCMA demonstrates the highest level of economic development efficiency (EDE), whereas green development efficiency (GDE) exhibits lower levels compared to other dimensions. Furthermore, development efficiencies across all dimensions show a decline over time. (4) Spatially distributed patterns reveal significant agglomeration areas for HQDE within the CCMA region. High-high agglomeration areas are predominantly concentrated in the central region of Changchun and southern region of Liaoyuan while low-low agglomeration areas primarily exist in northwest Songyuan and specific counties within Changchun. To attain HQD of the CCMA, it is advisable to bolster the economic scale of the central city, mitigate developmental disparities between counties and cities, and expedite green transformations in old industrial cities. These findings offer a valuable point of reference for optimizing resource allocation at the metropolitan level and devising strategies to foster regional HQD.

“…The Three Gorges Reservoir Area (TGRA) is located in the upper reaches of the Yangtze River (105 49′~110 12′E, 28 28′~31 44′N), in central and western China (Figure 1). The Three Gorges Reservoir Area covers an area of about 58,000 square kilometers (Zhang et al, 2022), starting from Yichang, Hubei in the east, and Chongqing in the west. It belongs administratively to the provinces of Chongqing and Hubei and includes 26 counties: 22 counties in Chongqing and 4 counties in Hubei.…”

The integrity and health of the ecosystem is the material basis for the common prosperity of different minority areas. Since the acceleration of social and economic growth in the 21st century, excessive social development has caused ecological imbalance, climate change and environmental pollution and other problems. The irrational use of natural resources gradually affects the balance between man and nature. In this paper, the characteristics of ecosystem health and four sub-systems of environment, economy, society and management in the Three Gorges Reservoir area are selected to study. The purpose of this paper is to construct an ecosystem health evaluation index system to describe the characteristics of the ecosystem in the Three Gorges Reservoir area. Firstly, a multi-criteria evaluation model was established based on catastrophe theory to evaluate the health of the ecosystem in the Three Gorges Reservoir area. Secondly, the Catastrophe progression method (CPM) was used to describe the overall change trend of the ecosystem in the Three Gorges Reservoir area from 2000 to 2016. The study shows that since 2000, with the development of economy and society and the further strengthening of environmental management, the health of the ecosystem in the Three Gorges Reservoir area has been improved year by year. At the same time, in order to further explore the factors affecting the ecosystem health of the reservoir, the climate factors were added to the control variables, and the model regression analysis was established through panel data. The final conclusion was that the average temperature, rainfall and sunshine time had significant effects on the ecosystem of the reservoir.

“…The Standard Deviational Ellipse (SDE) serves as a robust tool for the quantitative assessment of inherent spatial characteristics within a set of point elements (Zhang et al 2022), which excels in encapsulating the multidimensional spatial attributes of the focus area under examination. SDE consists of three core elements: the major axis, the minor axis, and the azimuth angle, which collectively provide a comprehensive depiction of both the trend and the dispersion extent of the data.…”

Spatiotemporal evolution pattern of carbon emission performance in Asian countries

<p>Due to extensive energy consumption and industrial production activities, Asian countries have become the largest sources of global carbon emissions, with emerging economies like China and India contributing significantly. Against the backdrop of increasing global climate change, carbon emissions have emerged as a focal concern within the international community. To mitigate these emissions, enhancing carbon performance is identified as a crucial endeavor. This study employs the Super-efficiency Slack-Based Measure (SBM) model to comprehensively evaluate the carbon performance of major Asian countries and delves into its influencing factors through factor analysis. Additionally, we utilize geographical methodologies to explore the spatiotemporal evolution characteristics of carbon performance in these countries. Preliminary results indicate that spatial centroid has gradually shifted towards the northeast, which could potentially reflect a geographic concentration change in some form of economic or industrial activity. Moreover, the elliptical parameters for carbon emission efficiency did not exhibit any discernible trend, maintaining a relatively stable overall pattern and distribution. The findings of this study hold significant implications for understanding the spatial heterogeneity and dynamic characteristics of carbon emission efficiency in Asia, and offer valuable insights for future policy-making.</p>
