“…The exogenous mode refers to expanding laterally on an urban scale, while the endogenous form refers to intensifying urban land use [5]. Accompanying the exogenous mode is often the occupation of numerous high-quality cultivated land, the destruction of the ecological environment, and the intensification of social contradictions [6][7][8][9]. Consequently, it is often considered as an unsustainable mode for city development.…”

Urban land intensive use is an important part of regional planning and plays an important role in the sustainable development of cities. However, the research on how to measure urban land use intensity is still controversial. This paper gives a perspective of multi-objective decision to explore the criterion of urban land use intensity in the process of urbanization. The theory of factor substitution was applied to analyze the mechanism of urban land intensive use in different urbanization stage. Additionally, the matching degree model (MDM), curve estimation model, and multi-objective programming model were employed in the case study of Wuhan urban agglomeration to give a multi-objective decision on urban land intensive use. The results show that the level of urban land intensive use lagging behind the level of urbanization development in more than 60% of the counties. When the level of urbanization is less than 30%, 30–70% and greater than 70%, the optimal intensity of urban land use characterized by fixed investments of unit land is 2.6252, 4.6132, and 6.7648 million RMB respectively. Based on optimal intensity, the counties in Wuhan urban agglomeration were divided into key development zone and optimized development zone. Finally, different management strategies were designed for different zones for urban land intensive use.

“…An increase in the urbanization (urb) significantly reduces environmental governance efficiency but improves environmental economic efficiency. The acceleration of the urbanization process may lead to some negative effects on environmental governance, but this does not mean that the size of the city should be reduced [58,60]. As long as the economic benefits brought by an increase in the urbanization can offset the costs that its environment can bear, the city can continue to steadily grow.…”

“…The main reason is that the acceleration of urbanization brings increasing amounts of polluting emissions and reduces the efficiency of environmental pollution treatment. However, the expansion of urbanization also brings a shift in heavy industry to the tertiary industry, thereby improving environmental and economic efficiency and increasing the degree of emissions trading [60,61].…”

An emissions trading system is a market instrument for pollution control that has been used in China for many years. The Ministry of Environmental Protection of China has approved the implementation of emissions trading pilot projects in 11 provinces since 2007, yet the effectiveness of the policy has not been comprehensively estimated. With panel data from 29 provinces and cities in China between 2003 and 2012, this study uses the data envelopment model-slack based measurement (DEA-SBM) method to measure environmental efficiency indicators and a difference in difference (DID) model to examine the impact of the emissions trading system on environmental efficiency. The results indicate that the policy has significantly improved environmental efficiency in the pilot provinces. However, the effects are heterogeneous with different efficiency levels across the diverse regions. Higher impacts were found in the central and western regions. Some suggestions for the optimization of the emissions trading system are suggested in this study.

“…To estimate the urban and suburban socio-economic development level, a comprehensive estimation is conducted. Referring to existing studies [53][54][55][56] and adjusting to the local situation, a series of social and economic indicators to reflect the regional development level was selected, as shown in Table 2. Principal component analysis (PCA) is adopted to obtain a comprehensive estimation to avoid multicollinearity among the indicators.…”

In developing countries like China, urbanization is still occurring at a rapid pace. During urbanization, the urban land expands drastically, which makes suburbs the most affected area facing urban expansion. The land transition has proven to threaten the function and security of ecosystems, and therefore the topics of suburban land transition and ecological security have raised much attention. However, the urban-suburban interaction, which is one of the basic characteristics of suburbs, has been insufficiently considered. The urban-suburban interaction is developed based on the flows of people, materials, and information between urban and suburban areas, and it essentially reveals the relationship between human activities and land-use optimization. To fill the research gap, this study adopts a case study of Wuhan city, and first quantifies the urban-suburban interactions from a symbiotic perspective, and investigates rural residents and public buses to verify the estimated interactions. The results show that there is obvious heterogeneity in urban-suburban interactions in different suburban towns. Correlation analysis and geographic weight regression are then applied to demonstrate the relationship between the urban-suburban interaction and urbanization in the suburbs. Additionally, urbanization potential in the suburbs is estimated. Then, a suburban ecological security assessment is conducted by a "pressure-status-response" (PSR) model, and the urbanization potential that is estimated based on urban-suburban interaction is integrated as a "pressure" indicator. The comparison between the suburban ecological security assessment results based on considering and not considering urban-suburban interaction demonstrates the importance of considering urban-suburban interaction. This study contributes to the understanding of the complicated relationships of urban-suburban socio-economic, spatial, and ecological environments, and offers suggestions for suburban planning and ecological protection.Sustainability 2020, 12, 1600 2 of 22 and ecological threat [2][3][4][5]. Hence, studies on urban-suburban interaction have caught much attention in recent years.Despite the existing studies on urban-suburban interaction analysis, the effects of such interactions on land transition and the eco-environment are insufficiently discussed. Land transition is one of the biggest challenges that the suburbs face in both developing and developed countries. In developing countries, urbanization is occurring at a rapid pace and is accompanied by fast urban land expansion. During this process, a large amount of ecological land transits into the urban area, including natural land and cropland [6][7][8]. Developed countries also confront similar problems. For example, Salvati, et al. [9] concluded that the urban expansion in discontinuous and low-density Mediterranean regions threatens soil quality and vulnerable ecologies. Ustaoglu and Williams [10] pointed out that there is a significant land conversion from agricultural land to urban land i...
