Urban Chemical Industrial Cluster Area Restructuring and Determinants: A Case Study of a Typical Old Chemical Industry Area Along the Yangtze River, China

China is in a transitional period between urban renewal and industrial change.In this period,the focus has been on the suburbanization of enterprises and land transformation in old industrial areas,particularly areas with chemical industries.A life cycle theoretical framework was established to develop chemical industrial zones in the context of urban expansion and land function conversion.The long-term historical processes and mechanisms that transformed a typical old chemical industry area along the Yangtze River,Yanziji Area of Nanjing City were unveiled and comparatively analyzed.The study found that the entire life cycle of the case study area was formed through the combined action of different influencing factors.Traditional industrial location factors played important roles during the rise and continuity of the chemical industry zone,while unconventional environmental regulations and government policies drove its decline and transformation.In the transformation of the old chemical zone,the renewal and redevelopment of industrial land into higher-value residential land is a key link determining the feasibility of government fund compensation and the circulation of capital.These findings demonstrate that regional control and environmental regulation play crucial roles in determining the location of polluting industries and the renewal of urban industrial areas.This research enhances the understanding of the development history and reconstruction of chemical industry clusters and plots within megacities at a finer geographic scale.

New Perspectives on Restructuring of Old Industrial Areas in China: A Critical Review and Research Agenda

The restructuring of old industrial areas has been receiving much attention in regional development studies both in industrialized and emerging economies. Although ample Chinese-speaking studies have been published on the topic, most of them suffer from paying too little attention to dynamic multi-scalar interactions between firms, institutions, policies and places, as well as a too strong focus on individual cases. They also mostly disregard internationally recognized concepts and theories in the field. Based on these internationally recognized modern concepts, this paper therefore puts forward some potential avenues for future research on the evolution of old industrial areas in China, which should overcome existing deficits in the Chinese-speaking literature. It suggests that some evolutionary economic geography concepts such as path dependence, lock-in, path creation, relatedness, as well as multi-scalar institutional and leadership approaches have useful potentials to better understand the evolutionary processes and mechanisms of old industrial areas in China.

Strategies for Localized Transformation of Landscape in Old Industrial Areas: A Case Study of Xiadian Industrial Area in Xuzhou City

REGENERATION OF A DECAYING URBAN INDUSTRIAL AREA DRIVEN BY ENDOGENOUS HOME INDUSTRIES:A CASE STUDY OF MARÉFAVELA,RIO DE JANEIRO

Favelas are low-income urban communities in Brazil,and Maréin Rio de Janeiro has the largest cluster of favelas in the country.The prevailing view of a unique,regulated,and normative city conflicts with the reality of the continued expansion of the favelas,posing challenges for architects and urban planners in developing new strategies for integrating informal areas with the main city.This study focused on a decaying industrial area adjacent to the Maréfavelas and explored a sustainable path for improving both the quality of the built environment and the quality of life of the residents.Effective infrastructure and socioeconomic links between the favelas and the city were proposed.The home production model that emerged from the favelas inspired the use of the abandoned industrial area as a home-industry incubator.The study proposed an urban regeneration strategy involving a bottom-up industry-space process evolving from home industries to group industries,and finally to larger community industries.This strategy can accelerate Maré’s development and integration with the city of Rio de Janeiro.

Simulation of Old Urban Residential Area Evolution Based on Complex Adaptive System

On the basis of complex adaptive system theory, this paper proposed an agent-based model of old urban residential area, in which, residents and providers are the two adaptive agents. The behaviors of residents and providers in this model are trained with back propagation and simulated with Swarm software based on environment-rules-agents interaction. This model simulates the evolution of old urban residential area and analyzes the relations between the evolution and urban management with the background of Chaozhou city. As a result, the following are obtained ： （ 1 ） Simulation without government intervention indicates the trend of housing ageing, environmental deterioration, economic depression, and social filtering-down in old urban residential area. If the development of old urban residential area is under control of developers in market, whose desire is profit maximization, and factors such as social justice, historic and culture value will be ignored. （2） If the government carries out some policies and measures which will perfectly serve their original aims, simulation reveals that old urban residential area could be adapted to environment and keep sustainable development. This conclusion emphasizes that government must act as initiator and program maker for guiding residents and other providers directly in the development of old urban residential area.

A long way to go:impacts of urbanization on migrants’livelihoods and rural ecology in less industrialized regions

Urbanization,often coupled with industrialization,is generally considered as a boost for improving livelihood as well as alleviating ecological pressures of the rural areas.However,this experience needs to be tested in less industrialized areas,particularly where the urbanization is driven by non-economic factors such as urban public services and relevant government policies rather than employment opportunities.Taking two villages on the Qinghai-Tibet Plateau as examples,through the field investigation by using semi-structured questionnaires and in-depth interviews,and statistical data analysis,we explored the impacts of urbanization on migrants’livelihoods and the ecological conditions of their original village rangeland.We found that the disposable income and savings of emigrant households were less than the stay households,which might be correlated to the limited employment due to the lagged industrialization in the local township,and the mismatch between their traditional labor skills and the demands of urban services.Their home-village rangeland overuse was not alleviated since the increasing grazing pressure caused by the stay households,though the emigrant households intended to decrease the number of livestock on their home pasture.We concluded that the urbanization misaligned with local industrialization may fail to improve migrant livelihoods and local ecological conditions in less industrialized areas.Our research supplements the previous urbanization theory by highlighting the non-industrialization driven urbanization,and is particularly pertinent for the transitional countries worldwide.

The Influence of the Urban-Rural Income Disparity on the Industrial Structure—Taking the Yangtze River Delta Region as an Example

In this paper, the effect of the mediation effect is mainly used to test and analyze the regression model, and most scholars have studied the impact of the modernization of the industrial structure on the income gap. However, this paper is from another perspective, based on the social background of high-quality development, the main study is the impact mechanism of urban and rural income gap on the industrial structure, taking the Yangtze River Delta as the main research object, and specifically selecting 22 central cities in the Yangtze River Delta region, which is also one of the highlights of this study. The regression model is constructed by using the intermediary effect, and the four intermediary variables of fiscal expenditure (M1), fixed asset investment (M2), number of patent applications (M3), and total import and export (M4) are selected, which represent the role of the government, fixed asset investment, scientific and technological level and opening-up level, and study and analyze the inherent influence mechanism between each variable. Before doing specific research, I consulted the papers and literature of many other outstanding scholars, among which Cheng Yuhong and Cheng Chi’s “The Influence Mechanism of industrial structure of urban and rural income gap” [1] has great reference value for this paper. According to the research results, under the background of high-quality development in the Yangtze River Delta region, the expansion of the income gap between urban and rural areas will inhibit the upgrading of the industrial structure, so it is necessary to focus on building a new type of urbanization, accelerating the construction of an urban innovation system, optimizing the rural employment structure to narrow the income gap between urban and rural areas, and providing impetus for the continuous upgrading of the industrial structure.

Urban Heat Island Characterization and Isotherm Mapping Using Geo-Informatics Technology in Ahmedabad City, Gujarat State, India

India has witnessed tremendous industrialization in the last five decades. This has led to migration of masses from rural areas towards cities for jobs and businesses. With increase in the population, the demand for residences has also increased which has escalated growth of slum areas and haphazard planning in suburbs. City of Ahmedabad is one such urban metropolis in the state of Gujarat, India. Being the financial capital of Gujarat, population of the city has increased many folds since 1980s. Congested and unsustainable planning and increasing in the emissions from industries and vehicles in certain areas of the city have given birth to many climatic issues. One of these major problems is the Urban Heat Island (UHI) phenomena. This has increased the temperature by four to five degrees and has also severely affected air quality. Satellite based Remote sensing data can provide temperature information of various land use classes. Remote Sensing data along with in-situ surface measurements can help to identify urban heat island intensities and hotspots in the cities. A study on heat island characterization and isotherm mapping was taken up in Ahmedabad City. In the present study, Surface Heat Island (SHI) effect is studied using satellite data along with field measurements. Thermal infrared data from Landsat ETM band-6 have been effectively used for monitoring temperature differences of various land use classes in urban areas. The study aims to identify and study the urban hot spots using the data from LANDSAT-5 and field data collected using IR Gun in various zones of Ahmedabad City. The results of this study indicated that the surface temperature near industrial areas and dense urban areas was higher as compared to other suburban areas in the Ahmedabad City.

The Strategy of Outdoor Space Micro-Renewal under the Goal of Communities for All Ages: A Case Study of Xingchaibeiyuan Community in Nanchang City

With the rapid development of the city,the old city has gradually lost its former glory,and the old community accounts for a large proportion in the city,and is located in the core area of the city. At present,there are some problems in the old community,such as high degree of aging,poor quality of living space,and lack of outdoor space. The old community transformation is mainly in the way of ' guided reconstruction',it has completely destroyed the original historical environment and the spirit of the place. Therefore,taking Xingchaibeiyuan Community in Nanchang City as an example,we deeply explore the strategy of micro-renewal of community outdoor space,so as to provide a reference for the renewal of outdoor space in this kind of old residential area.

Reconstructing Social Capital to Promote Urban Redevelopment:A Case of Lianjiao Area in the Pearl River Delta Region

Guangdong Province started the so-called"three olds redevelopment"in 2009,aiming to advance industrial upgrading.Existing literature points out that appropriate distribution of land rent differential among the stakeholders like urban governments,village collectives,and developers is the most important determinant.Employing the theory of urban regime,the paper focuses on the redevelopment process of the Lianjiao Area in the Pearl River Delta region to reveal how the three entities(government,rural community,and developers)interact.It has been found that the local urban government is the main driver which facilitates the positive accumulation of social capital through the supply of redevelopment policy and fi nancial support.Through the reconstruction of trust of villagers and developers,the government gains the rights to coordinate the redevelopment.As the actual landholder,rural villages represent the profi ts of villagers in bargaining with the other two parties.The improvement in infrastructure and the formulation of detailed redevelopment plans increase the land rent differential,encouraging developers’participation in the redevelopment.The three entities form a negotiation-based development alliance and fi nally lead to successful redevelopment.
