Abstract Anthropogenic emissions of reactive nitrogen (Nr) result in adverse impacts on the ecosystems. Nowhere has that threat been more challenging than in rapidly urbanized China, the world's largest anthropogenic Nr producer. The Nanjing Declaration in 2004 called for global reductions in Nr emissions. To assess China's progress, multisource Nr emissions were evaluated with a quantitative method from 2004 to 2014. The results showed that national Nr emissions had increased with fluctuation over this period, 55–59% of the total Nr emissions were emitted to the atmosphere, and that agricultural production still was the biggest contributor (62–69%). The hotspots were mainly located in the developed and coastal regions that also have high population densities. Urbanization was associated with overall decreases in agricultural Nr emission and increases in industrial and residential Nr emissions. The overall increase in residential Nr emission per capita played a large role in driving the growth of national Nr emission. Continuing urbanization poses a significant challenge to future Nr mitigation for ecosystem sustainability and a range of strategies, covering improvement of N-use efficiency, slowdown of Western China's urbanization, and promotion of low N intensive lifestyle, are proposed that can promote Chinese low-nitrogen development. Graphical abstract Unlabelled Image Highlights • Anthropogenic Nr emissions from China have increased with fluctuation since Nanjing Declaration. • Urbanization has positive and negative two-way effects on Chinese Nr emissions. • Continuing urbanization poses a significant challenge to future Nr mitigation. • Regional Nr emissions possess mitigation potentials with the promotions of low-N strategies.

With the accelerating urbanization in China, the right-of-use transfer (RUT) of rural collectively owned construction land provides a promising means of increasing the efficiency of rural land use and promoting urban and rural integration. There are various ways of doing this and no universal mode of RUT that fits all areas because of the divergent cultural characteristics and geographical features of different regions and locations in China and decisions need to be made on a case-by-case basis. This paper proposes an analytical framework to help in such decision making. Firstly, the literature concerning the RUT of collective construction land is reviewed and six typical pilot reform areas are studied. Secondly, a theoretical analytical framework for the choice of RUT mode is developed based on the findings of the literature review and the experiences of the pilot reform areas. Thirdly, Zhoushan City's new urban district is used as a case study to demonstrate and test the framework, and an appropriate RUT mechanism is suggested. The analytical framework can serve as a guideline for local governments to make decisions on the form of collective construction land RUT throughout China. [ABSTRACT FROM AUTHOR]

Land suitability assessment is a fundamental process in various types of space control planning and land development, due to its effects on proper land use and reasonable urban layout. However, this form of assessment has also received much criticism for its theoretical and empirical deficiencies. This study aims to review Chinese land suitability assessment from the perspective of rainfall-waterlogging focusing on the Su Yu Yuan area in Changsha. It finds that more than half of the land in the Su Yu Yuan area that is assessed as (very) suitable for urban development has high risk of rainfall-waterlogging. The prevailing Chinese land suitability assessment method is therefore deficient as it cannot accurately reflect the rainfall-waterlogging risk of land use. To refine the land suitability assessment, it is suggested that either (1) the indictor “inundation degree of flood” is replaced with “rainfall-waterlogging risk” or (2) rainfall-waterlogging risk assessment results are superimposed onto land suitability assessment results for regions with plentiful rainfall and low-lying terrain.

Urban growth management is a popular topic for study area all over the world. Despite the increasingly rich literature, however, little has been considered of the complex relationship between the various urban development factors and their feedback structure. This paper contributes in understanding the mechanism of, and establishing a link between, urban growth management oriented by zoning in China (namely development priority zoning or DPZ). A system dynamics urban growth model is presented that is integrated with China's socio-economic development situation. With Yiwu city and Qingtian County as case studies, the model is applied in simulating urban growth under different driving modes. The results indicate that the DPZ in these two areas has an influence on urban growth management strategy, with the driving mode of urban growth affecting economic development levels, migration and types of land conversion. It is concluded that different driving modes are needed for different types of regions according to the functional positioning of their DPZ and that the model contributes to their identification.

China is facing the challenge of sustainable urban redevelopment due to its massive economic transformation process. As a unique product of the rapid urbanization of past decades, urban village has become a major obstacle for sustainable redevelopment because of its sub-standard infrastructure and disordered built environment. Redevelopment of ‘villages in the city’ (ViCs) is distinct from normal urban redevelopment because it involves the change of collective land ownership without de jure property rights to state land ownership with de jure property rights. What site characteristics, what ownership type, what geographical characteristics, make village sites more likely to be redeveloped? This study addresses this question with particular reference to industrial sites in Shenzhen. An analytical framework is developed based on the concept of rent gap to analyze the possible effects of these factors. An empirical investigation is conducted based on a set of data that covers all 44 village-owned industrial sites in the Nanshan District in Shenzhen. The findings suggest that village sites with better accessibility to good transportation facilities and the city centre are significantly more likely to be redeveloped and thus will be integrated into formal urban areas earlier than those located in less accessible areas. It is also demonstrated that fragmented land ownership and lack of legal land rights are not significant barriers for the sustainable redevelopment of such sites. [ABSTRACT FROM AUTHOR]

Along with China's modern industrialization, challenges on smog crisis are raising dramatically in the past decade. The sources of municipal smog are multiple and complex, one of which is construction dust emission due to the rapid urbanization. In literature, there are studies focusing on the end-pipe treatment of construction dust; however, very little research has been conducted from the perspective of dust mitigation in developing countries. To fill in this research gap, this paper investigates the current situation of construction dust prevention and control in China, with the aim of providing insights for mitigating dust pollution caused by the construction industry. Through a combination of the content analysis, on-site observation, questionnaire survey and interviews with experienced professionals, a total of 11 related regulations are thoroughly reviewed, and the main sources of construction dust production are identified. A case study is further presented to demonstrate the prevailing dust control measures on site. Recommendations are proposed in order to increase the awareness of related stakeholders, including formulation of targeted regulations, establishment of an appropriate charging scheme, development of a feasible monitoring system, and enhancement of training and dissemination.

With the level of urbanization in China now exceeding 50%, its collective rural land system is under increasing pressure, creating conditions in which there is increasing conflict between the efficient use of land for agricultural purposes and its retention as security for the rural population. This paper first examines the fundamental nature of China's collective land system by analyzing the collectivization history of China, then provides a comprehensive appraisal of the strengths and weaknesses of the collective land system's role in history and the challenges it faces in modern times. The main changes needed for the current collective system are identified as (1) the establishment of a new transfer mechanism for potential collective construction land, (2) the completion of land rights verification and consolidation work, and (3) the endowment of villagers with more rights to enjoy the distribution of land incremental value. The paper's main contribution is to question the relevance of collective rural land system in contemporary China, where a shift is now taking place from one of pure economic development to one involving more social concerns, and propose potential viable amendments to integrate the need for both perspectives.

In current practice, urban-rural development has been regarded as one of the key pillars in driving regenerative development that includes economic, social, and environmental balance. In association with rapid urbanization, an important contemporary issue in China is that its rural areas are increasingly lagging behind urban areas in their development and a coordinated provision of public facilities in rural areas is necessary to achieve a better balance. A model is therefore introduced for quantifying the effect of individual infrastructure projects on urban-rural balance (e-UR) by focusing on two attributes, namely, efficiency and equity. The model is demonstrated through a multi-criteria model, developed with data collected from infrastructure projects in Chongqing, with the criteria values for each project being scored by comparing data collected from the project involved with e-UR neutral “benchmark” values derived from a survey of experts in the field. The model helps evaluate the contribution of the projects to improving rural-urban balance and hence enable government decision-makers for the first time to prioritize future projects rigorously in terms of their likely contribution too.

The inverted-U relationship between urbanization and urban-rural inequality has been relatively widely observed and investigated. However, most are confined to the context-specific empirical evidence and a certain measure of inequality. Furthermore, the discussions concerning the mechanism involved deserve focus and extension, particularly with the goal of new-type urbanization in China. This study aims to provide an analytical framework of the distribution effect of urbanization. It includes mathematical deductions based on the Gini coefficient and Theil's index, and empirical evidence relating to both the nexus and mechanisms across Chinese provinces based on panel models and mediating effect models. The key findings are threefold. Firstly, the inverted U urbanization-inequality nexus has been substantiated both theoretically and empirically, and most Chinese provinces have experienced the 'decoupling' between urbanization and urban-rural income inequality. Secondly, such relationships are regionally heterogeneous in China, which is less significant in the northeast region but quite significant in the eastern and western regions. Finally, urbanization can play a key role in narrowing the income gap between the urban and rural areas through increasing fiscal expenditure on urban-rural affairs and reducing that on science, education, culture, and health. Nevertheless, the mediating effect of local fiscal expenditure on agricultural issues is relatively insignificant. These conclusions not only provide both theoretical and empirical support for the urbanization-inequality Kuznets curve, but also specify and expand insights into the mediating role of the local fiscal expenditure structure in the pursuit of China's new-type urbanization. • The inverted U urbanization-inequality nexus is substantiated theoretically and empirically. • Most Chinese provinces have experienced the 'decoupling' between urbanization and urban-rural income inequality. • The inverted U urbanization-inequality nexus is regionally heterogeneous. • Increasing fiscal expenditure on urban-rural affairs and reducing that on science, education, culture, and health have mediating effects involved.

China has experienced considerable economic growth since 1978, which was accompanied by unprecedented growth in urbanization and, more recently, by associated rising urban housing and land banking issues. One such issue is that of land hoarding – where real estate developers purchase land to hold unused in the rising market for a future lucrative sale, often several years later. This practice is outlawed in China, where land use is controlled by increasingly strengthened Government policies and inspectors. Despite this, land hoarding continues apace, with the main culprits being the developers and inspectors working subversively. This resembles a game between two players – the inspector and the developer – which provides the setting for this paper in developing an evolutionary game theory model to provide insights into dealing with the dilemmas faced by the players. The logic and dilemma of land banking strategy and illegal land banking issues are analysed, along with the land inspector's role from a game theory perspective by determining the replication dynamic mechanism and evolutionary stable strategies under the various conditions that the players face. The major factors influencing the actions of land inspectors, on the other hand, are the costs of inspection, no matter if it is strict or indolent, conflict costs, and income and penalties from corruption. From this, it is shown that, when the net loss for corruption (income from corruption minus the penalties for corruption and cost of strict inspections) is less than the cost of strict inspections, the final evolutionary stable strategy of the inspectors is to carry out indolent inspections. Then, whether penalising developers for hoarding is severe or not, the evolutionary strategy for the developer is to hoard. The implications for land use control mechanisms and associated developer-inspector actions and counteractions are then examined in the light of the model's properties. [ABSTRACT FROM AUTHOR]

Abstract: Implementing international projects in a foreign country is a high risk business activity. Research on this subject has tended to emphasize traditional risks. However, an emerging new type of “social risk” in the globalization era has been ignored. With the rapid urbanization progress in China, many international contractors have entered the Chinese construction market due to the huge demand in the market. However, the differences in the social, economic and cultural backgrounds among the international contractors and their partners have led to difficulties and occasional disputes among various participants. In particular, they are presented with various social risks in a new environment. This paper identifies the key social risk factors associated with international contractors from a questionnaire survey and case study. The social risks highlighted from the questionnaire survey include “local protectionism (for local projects)”, “risk of poor social relations between various parties in the local region”, “permit or license risk in dealing with land use and construction planning issues due to policy changes” and “dispute risk with local construction labor”. Several risk response strategies for international contractors are also illustrated by the case study from China. Suggestions developed in the case study can provide useful references to those international contractors who have entered or are planning to operate their businesses in China.

Over the last couple of decades, urban areas around the world have been engaged in increasing initiatives, practices and experiments with a view to achieving social, economic and environmental sustainability. Echoing these movements, sustainable urbanization has entered many policy agendas. In practice, various aspects including eco-environmental protection, land development, housing, policy, population growth and migration and energy utilization have been noted and discussed by different scholars. In the context of China, these terms/keywords are found in studies across different scales and types of cities, each of which would have implications for our understanding of theory relating to sustainable urbanization. In response, this paper reports on a comprehensive literature review of these studies of sustainable urbanization, and further explores three key areas including evaluation, innovative solutions and engagement of all stakeholders that will move forward sustainable urbanization process across cities in China.

In recent years, China has undergone an extremely rapid phase of urbanization, which has caused many acute problems between urban and rural areas. This paper identifies three categories of social, economic and environmental conflict, and investigates their significance according to the views of two different populations using a questionnaire survey and interviews. Using fuzzy set theory, the key causes of urban-rural conflict related to urbanization in China are identified. The differences in urban and rural people's perceptions of these key factors are discussed and the factors underlying these perceptions are analyzed. [ABSTRACT FROM AUTHOR]

Urban and rural areas are two different yet coexisting systems. Developing countries such as China have been undergoing a rapid urbanization process. However, urbanization often causes competition for land resources between urban and rural areas, and such competition can result in conflicts between the two systems. To identify the risk factors of urban-rural conflict, this paper utilizes a research framework including content analysis, brainstorming and semi-structured interviews. The results indicated that the main risk factors between urban and rural areas comprise conflicts in property, resources and development. Suggestions are proposed to reduce the conflicts occurring between urban and rural areas during the urbanization process. [ABSTRACT FROM AUTHOR]
