Green transformation paths of resource-based cities in China from the configuration perspective

Green transformation is an unavoidable choice for resource-based cities(RBCs)that face resource depletion and environmental pollution.Existing research has focused primarily on specific RBCs,making it challenging to apply green transformation strategies universally across cities.The fuzzy set qualitative comparative analysis(fsQCA)is a combination of qualitative and quantitative analyses that can handle multiple concurrent causality problems and determine how different conditions combine into configurations and generate an outcome.Thus,to address this gap,in this study,we established a research framework for green transformation and utilized the fsQCA to examine the configurations of 113 RBCs in China.By incorporating the element of time,this study explored the dynamic evolution of solutions in 2013,2016,and 2019.The main findings indicate that individual elements do not constitute the necessary conditions for improving the green transformation efficiency(GTE),and the systematic combination of multiple conditions is an effective path for realizing the improvement of the GTE in RBCs.Green transformation paths of RBCs exhibit the same destination through different paths.Additionally,the combination of system environment elements and system structure elements is both complementary and alternative.Differences in RBCs have led to various factor combinations and development paths,but there are some similarities in the key elements of the factor combinations at different stages.Economic environment,government support,and technological innovation are key factors that universally enhance the GTE in RBCs.These insights can assist city managers in formulating policies to drive green transformation and contribute to a better theoretical understanding of green transformation paths in RBCs.

An Enhanced Multiview Transformer for Population Density Estimation Using Cellular Mobility Data in Smart City

This paper addresses the problem of predicting population density leveraging cellular station data.As wireless communication devices are commonly used,cellular station data has become integral for estimating population figures and studying their movement,thereby implying significant contributions to urban planning.However,existing research grapples with issues pertinent to preprocessing base station data and the modeling of population prediction.To address this,we propose methodologies for preprocessing cellular station data to eliminate any irregular or redundant data.The preprocessing reveals a distinct cyclical characteristic and high-frequency variation in population shift.Further,we devise a multi-view enhancement model grounded on the Transformer(MVformer),targeting the improvement of the accuracy of extended time-series population predictions.Comparative experiments,conducted on the above-mentioned population dataset using four alternate Transformer-based models,indicate that our proposedMVformer model enhances prediction accuracy by approximately 30%for both univariate and multivariate time-series prediction assignments.The performance of this model in tasks pertaining to population prediction exhibits commendable results.

Discussion on the Problems and Path of Characteristic Town Construction in Underdeveloped, Resource-Based Cities: A Case Study of Ganzhou City

Characteristic towns as a characteristic industry are one of the important measures of China's new urbanization strategy. The construction of characteristic towns in different regions needs to pay attention to regional differentiation. At present, the research on characteristic towns focuses on the developed the developed central and eastern regions. There are still few studies on characteristics towns in underdeveloped areas. Starting from the analysis of the concept of the characteristic town, this paper sorted out the general situation of the construction of characteristic towns in China based on the existing research literature, selected Ganzhou City for research, pointed out there were "two restrictions and two singles" in the construction of characteristic towns in Ganzhou City, and clarified that the characteristic towns of Ganzhou City should adhere to the construction path of "two characteristics and two integrations", with a view to providing a useful reference for in Ganzhou City the construction of characteristic towns, industrial transformation and upgrading, and poverty alleviation in such underdeveloped, resource-based cities.

Characteristics and Mechanism of Agricultural Transformation in Typical Rural Areas of Eastern China:A Case Study of Yucheng City,Shandong Province

Rural off-farm employment,rapid loss of agricultural land,and advanced technology popularization had led agricultural production in Chinese typical rural areas come at a critical transformation and upgrade stage.Based on sample survey data gathered from 401 households in Yucheng City,Shandong Province,this paper focuses on the characteristics and mechanism of agricultural transformation in typical rural areas of the eastern China.It was found that 74.3% of households surveyed kept at least one member engaging in off-farm employment,and 57.1% looked forward to expanding the operational scale of arable land,while just 13.7% had actually transferred their agricultural land.Since growing off-farm employment does not result in the collapse of traditional subsistence agriculture,therefore,agricultural production in Yucheng City is at an incomplete transformation phase from traditional small-holder farming to modern scale economy.It is caused by both macro environments and family characteristics,while urban-rural dual structure,imperfect rural development policy and agricultural technology popularization make peasant economy strengthen upon maintenance,and small-holder farming becomes peasant's natural response owing to pluriactivity,local off-farm employment,reverse elimination,etc.In order to achieve smooth agricultural transformation of typical rural areas in the eastern China,it needs to promote professional differentiation among peasants,under clear policies adopted by central government.Providing comprehensive services for agricultural production and improving production skills and knowledge of farmers who are still living in the countryside will effectively stimulate the process of agricultural transformation.

Conceptualizing and Measuring Economic Resilience of Resource-based Cities： Case Study of Northeast China

This paper develops a conceptual model and an indicator system for measuring economic resilience of resource-based cities based on the theory of evolutionary resilience and the related concepts of persistence, adaptation, and transformation. Nineteen resource-based cities in Northeast China were analyzed using the indicator system. The results showed that Liaoning and Jilin provinces had higher economic resilience than Heilongjiang Province. Panjin, Benxi, and Anshan in Liaoning Province were the top three cities, while Shuangyashan and other coal-based cities in Heilongjiang Province ranked last. Metals-and petroleum-based cities had significantly higher resilience than coal-based cities. The differences in persistence, adaptability, transformation, and resilience among resource-based cities decreased since the introduction of the Northeast Revitalization Strategy in 2003. Forestry-based cities improved the most in terms of resilience, followed by metals-based and multiple-resource cities; however, resilience dropped for coal-based cities, and petroleum-based cities falling the most. The findings illustrate the importance and the way to develop a differentiated approach to improve resilience among resource-based cities.

The Evolution and Differentiation of Economic Convergence of Resource-based Cities in Northeast China

A key target of the overall strategy implementation for regional development since the 18th Party Congress of China has involved taking measures to narrow regional disparities. This is because resource-based cities' economic development has fallen below general levels due to resource exhaustion and an unbalanced industrial structure, among other factors. Further, an economic gap has long existed between Northeast China's large number of resource-based cities and non-resource-based cities. This article comprehensively studies the economic convergence of Northeast China's resource-based cities and non-resource-based cities from 1996 to 2015 by using a dynamic panel to analyze not only the economic development of different industries and types of cities, but also the main factors that influence economic development. The empirical results demonstrate that economic convergence exists in both resource-based and non-resource-based cities, but the economic gap between them has clearly narrowed since the implementation of a strategy to revitalize the Northeast's old industrial base. Shrinking cities are the fastest to converge, as mature cities are slower and regenerating cities are the slowest; regarding industry structure, the secondary industry dominates the economy in mature and shrinking cities, and the tertiary industry in regenerating cities. The primary stimulus in resource-based cities' economic development involves upgrading the industrial structure and investing in human capital. As China faces a ‘new normal' economy, resource-based cities in Northeast China should restructure the economy and perfect their market system to avoid again widening the economic gap.

Geographical Space Development Zone Classification:An Essential Guide for Transformation of Mountain Resource Cities

Sustainable development of mountain areas and resource cities has been a significant issue worldwide. Transformation of mountain resource cities is facing tremendous difficulties. In the context of National Major Function-oriented Zone Planning raised to a national strategic level in China, it is important to effectively implement the planning by studying geographical space development zone classification of prefecture- and county-level cities based on their major function orientation. This research is even more critical for the transformation of mountain resource cities. In this study, we evaluated geographical space development suitability, and classified geographical space development zones for Dongchuan Distric in Kunming City of Yunan Province, China, a typical mountain resource city. A quantitative grid-based evaluation was conducted using key-factor identification and restrictive-supportive comprehensive index determinati based on a geographic information system framework with different source data. The results included a classification of geographical space of Dongchuan into five types: the prohibited development zone, the inappropriate development zone, the controlled development zone, the moderate development zone and the preferential development zone. The distribution characteristics of geographical space development zones showed that the proportion of the prohibited development zone is the highest, while that of the other four development zones is comparatively lower and significantly fragmented. The geographical space development suitability is greatly controlled by the geomorphic pattern. Although Dongchuan is extremely restrained in terms of suitable geographical space for industrialization and urbanization, it still has the certain preferential and moderate development zones with an area of 207.81 km2 with large parts being concentrated and contiguous, which makes these areas the most favorable for development. Only by adapting to this reality and implementing centralized development strategy in the regions with higher suitability may Dongchuan achieve smooth transformation from expansion mode to compact mode and its sustainable development capacity may be improved. Suggestions with an angle of industrial and spatial development pattern were put forward for the transformation of the city in future.

Megacity pathways in China under the dual carbon goal:The case of Shanghai

The pathways to achieving carbon neutrality at the city level are diverse due to varying energy supply and demand conditions.Shanghai faces obstacles such as limited land resources,high costs of renewable energy technologies,and instability of renewable energy.These challenges hinder the city’s efforts to achieve carbon peak and carbon neutrality(dual carbon).Therefore,Shanghai must identify and optimize its development path for renewable energy under the dual carbon goal.We employed the Low Emissions Analysis Platform Shanghai(LEAP-SH)model to simulate the impact of policies,such as industrial upgrading,energy efficiency improvement,energy structure optimization,increased technical innovation on energy,and ecological restoration,on the carbon emission pathways from 2022 to 2060 using five different scenarios.Our results indicate that Shanghai has the potential to achieve carbon neutrality in 2059 by promoting carbon reduction,pollution control,and green expansion.Moreover,we determined that the manufacturing industry;power generation industry;and transportation,storage,and mail services are the three major sectors for emission reduction under the dual carbon goal.Furthermore,the capacity and output of coal-fired power plants will be gradually replaced by offshore wind power in the dual carbon pathway.Finally,this study proposes countermeasures and suggestions for Shanghai to attain the dual carbon goal and high-quality development.

Urban structure transformation of Lhasa City after the peaceful liberation and democratic reform of Tibet

In Tibet, Buddhism coupled with its theocratic history has given its cities and urban areas unique forms and structures. As the political, religious, and economic center of Tibet, Lhasa City has a special urban form and has experienced typical urban transformation processes for a thousand years. The city has been experiencing significant urban structure transformation that has accompanied the socio-economic development in recent decades since the peaceful liberation and democratic reform of Tibet during the 1950 s. Hence, this study presents the time-series of urban structure changes in Lhasa City for the purpose of understanding the characteristics and mechanisms of transformation under the republican political system. First, the study illustrates the urban socio-economic changes of Lhasa City beginning in the 1950 s via statistical data analysis. We then divide the urban development into several stages. Subsequently, we identify the transformation characteristics of urban structure by investigating urban growth, street structure, land-use, and religious facilities via maps of the city from every development stage. This paper ultimately discusses the regulation of city transformation. This study clarifies several probable issues facing Tibetan cities and proposes suggestions for future urban development of Tibetan cities.

An Outlook of Housing Transformation in Dhaka City

This paper contributes to the view that urban housing in most cities in developing countries is different in nature and more extent than that operative in developed countries.It addresses the emergence of multi-storied apartments through transformation in residential areas in Dhaka,one of the populous cities in the world and largest metropolitan region in Bangladesh,with a particular reference to a study conducted at Rupangar Residential Area.It identifies the key forces and processes underlying Dhaka’s residential transformation and the advent of multi-storied apartments.Fragmentation of functions and the uses of building stocks in relation to the socio-economic aspects with local conditions were sought in the survey.The increasing housing demand is essentially fulfilling by multi-storied apartments and steadily transforming the landscape and lifestyle of huge urban dwellers in Dhaka.It reveals from the study that apartment living gains much popularity and the dominance of informal apartments over formal apartments is more evident.More distinctly,piecemeal apartment development by the informal developers provides affordable shelter to the highest segment of city dwellers and Rupnagar presents a reasoned scenario urban housing transformation in the capital of Bangladesh.

Trends of the Transformation of Urban Form in Arab Cities with Specific Reference to AI-Khobar

The paper analyzes the current trends of urban transformation and delineates an underlying rationale which enables the comprehension of the current character of Arab city with particular reference to Al-Khobar. The city form is subjected to a re-reading arguments of which are based on critical interpretation of the mechaitisms of urban morphology in relation not only to the impacts of global economy and building boom but also to the means of perception of urban space by different strata of the urban realm. Thus, urban morphology of the city is studied as a medium which manifests a dissociation, and thus duality, between social structure and its physical container. The paper further argues that uncritical import of urban and architectural typologies seem to create a peculiar type of urban-architectural forgery that is usually reduced to skin-deep facade mimicry. Particularly, solo performances of shiny high-rise buildings and sharp contrasts of street fronts between main arteries and back streets depict impressions of fragmentation and segregation. The emerging urban-scape that can be associated with the cultural and economic leap in Arab regions today is critically evaluated. Thus, the paper proposes judicious and critical planning policy instead of direct import of global urban-architectural typologies.

Study on Correlative Issues about State-owned Enterprises Restructuring in Resource-based Cities in China

The ＂sediment＂ formed in the process of long-term development of the resource-based cities not only restricts the economic structure trans/brmation, but also increases the difficulties for restructuring the state-owned enterprises. Furthermore, it makes current ways of reforming staffs＇ identity replacement and managers＇ shareholding mode inefficient in state-owned enterprises reformation in resource-based cities. According to the characteristics of resource-based cities and property right reform theory, cash and share right compensation for the different staffs in the process of staffs＇ identity replacement have been identified. In addition, different profitable investment policies have also been suggested. For managers＇ share holding, the stimulant share ownership should be adopted principally, at the same time corresponding restrictions should be set up for managers＇ investment share ownership due to share ownership structure.
