摘要：
Unsecured property rights to rural housing land (RHL) have impeded the development of the RHL market, resulting in inefficient rural land-use and resource allocation in China. The Chinese government implemented the rural land titling program as an institutional reform to provide rural households with secure property rights to RHL. The program has been implemented since 2011, yet its effects upon RHL transfers have not been adequately investigated through empirical studies. Here we conducted household surveys in 39 villages consisting of inner-suburbs, outer-suburbs, and scenic rural areas in Hubei Province, China, and received valid responses from 361 households. Descriptive statistics were used to explore and summarize this survey data, and a difference-in-differences (DID) regression model was built to examine the effects of land titling on RHL transfer. Three main results were found: (1) Land titling significantly promoted RHL transfers in the inner-suburbs but contributed little to RHL transfers in the outer-suburbs or scenic rural areas. (2) The effect of land titling on RHL transfer depended significantly on how rural households interpreted the institutional reform: it proved more effective where there already existed a market for RHL transactions, and rural households have recognized the market value and expect secure property rights to RHL. (3) Household characteristics, such as the number of persons, the income and employment structure, the quantity and size of RHL possessed, also impacted decision-making regarding RHL transfers; hence, they influenced households’ susceptibility to the effects of land titling. The findings of this research suggest area-specific policies for the Chinese government to deepen the institutional reform of RHL and improve the overall efficiency of rural land allocation.

Yangtze river economic zone;Wastewater discharge;Spatial-temporal pattern;LMDI
摘要：
This study uses Exploratory Spatial Data Analysis (ESDA) method and Logarithmic Mean Divisia Index (LMDI) model to analyze and discuss the Spatial-temporal pattern as well as the dominant driving factors of wastewater discharge in Yangtze River Economic Zone from 2002 to 2015. The paper indicates that: (1) In terms of the spatial-temporal pattern, the amount of wastewater discharge in Yangtze River Economic Zone shows an increase trend from 2002 to 2005, and then put up a decline trend between 2005 and 2015. Referring to the spatial characteristics, firstly, the amount of wastewater discharge increases from upstream to downstream. There are few high discharge cities whereas more low and middle discharge cities. Secondly, a certain amount of wastewater discharge transfers from the downstream to the midstream and upstream, and the wastewater discharge in mountainous area is lower than other regions. (2) In terms of the change of spatial relationship among cities in the research area, the wastewater discharge shows a significant spatial agglomeration. High discharge cities are concentrated in the Yangtze river delta and low discharge cities are distributed in underdeveloped areas in the western part of China, especially the tourism-oriented cities. (3) In terms of the driving factors, the technical improvement effect did a negative contribution and controlled the amount of wastewater discharge, whereas the industrial structure effect did a positive or a negative contribution depend on the policy and market. The economy development effect, which was one of the dominant factors, did a positive contribution to the amount of wastewater discharge. Moreover, the population scale effect did a positive contribution to the wastewater discharge, but the impact is not significant.

摘要：
Developing countries generally face the challenge of significant urban-rural divides during their process of industrialization and urbanization. Following the paradigm of the theory of urban bias (TUB), this article focuses on the urban-biased land development policy (UBLDP) in contemporary China, which refers that local governments expropriate rural land with the inadequate compensation and use a considerable share of net land revenue to develop urban areas instead of rural areas. On the basis of pointing out three practical facts about and proposing the technique to measure the UBLDP, its influence on the urban-rural income gap (URIG) is investigated by employing the GMM dynamic model along with panel data from Hubei Province over the period of 2010-2016. The results show that a 1% increase in the extent to which compensation deviates from the market value of expropriated rural land (ERL) leads to a 0.46% increase in the URIG, while this effect is attributed to an unbalanced urban-rural income growth associated with the land development. These findings not only generate a broad of direct implications for Chinese policymakers but also provide lessons for other developing countries.

摘要：
Dramatically increased societal demands on the municipal services that contradict environmental protection and information processing capability oriented to resource utilization efficiency suffer from opposing simultaneous requirements. The smart city provides better solutions for urban areas which are increasing at an unprecedented speed. This paper presents an empirical study carried out to assess and analyze the development pattern of 35 smart cities in China using the principal component analysis (PCA) and back propagation (BP) neural network techniques. The proposed PCA-BP neural network assessment processing model is applied with six dimensional factors and twenty-two operating indices. With the feature extraction and performance score calculated via PCA, BP neural network is adopted for city classification to recognize the development differences in smart cities. The results indicate that the factor-driven impetus evolves into innovation-driven impetus, narrowing the gap from the holistic perspective between the first and middle-ranking groups, while two middle-ranking groups show a similar upward trend in terms of developing a smart economy through sustainable productivity in innovative enterprises and high-tech industry. To some extent, in response to a similar improving trend in the application of smart services, a distinct advantage of an individual index can be a complementary offset to unapparent holistic highlighting the reception of the lowest average points. Unbalanced development exists in two subaverage groups that are deficient in the initial inventory of smart infrastructure and demands. A relatively large difference exists in the smart mobility index among cities, whereas the opposite case is found concerning the smart environment index. Finally, corresponding optimized development pattern are recommended for building a sustainable smart city. (C) 2019 Elsevier Ltd. All rights reserved.

摘要：
Electronic tax filing and payments system ETFPS) is a kind of foundational information technology application in the initial stage of Egovernment in developing countries. By introducing variables like system quality and perceived security, as well as decomposing important variables like social influence and perceived behaviour control, this study integrates Technology Acceptance Model (TAM) and Theory of Planned Behaviour (TPB) to explain the factors motivating the acceptance of ETFPS in Tanzania. Empirical outcomes demonstrate that system quality significantly influences perceived usefulness and perceived ease of use of ETFPS. Perceived usefulness and perceived ease of use significantly influence the users’ attitude towards accepting ETFPS, which further affects their behavioural intention. Moreover, perceived security, mass media influence, and external facilitating condition have a significant impact on the users’ behavioural intention. The user’s intention determines their actual use of ETFPS. This study further provides some managerial implications for policymakers to design and promote further acceptance and use of ETFPS.Keywords: E-Government Acceptance, E-Tax Filing and Payments System (ETFPS), Technology Acceptance Model (TAM), Theory of Planned Behaviour (TPB), Tanzania

摘要：
In a city, housing price varies with location. Thus, housing price plays an important role in detecting the spatial pattern of the city. Spatial interpolation methods have been widely used for simulating and predicting urban housing prices. In this paper, the Ordinary Kriging interpolation method is used for producing the digital elevation model (DEM) of urban housing prices. Based on the three-dimensional DEM of urban housing price, this paper develops a novel approach for geo-visual analytics of urban housing prices. To investigate and visualize the spatial morphology of housing price, we design the Water-flooding, Section-cutting and Belt-floating methods, and implement these methods with the 3D-analyst module in GIS environment. Then, we take Wuhan City as a case, apply this approach to analyze the complex spatial morphologic characteristics of the DEM for housing price and visualize the results from the multidimensional perspectives. The results show that the Water-flooding method effectively supports the investigation of the top areas of surface changes; Section-cutting method performs well in examining the profile or cross-section of the urban housing surface; and Belt-floating method is helpful for detecting the spatial variance of the urban housing surface through the routes of specific lines. The results demonstrate that the proposed approach works better than traditional methods in describing the complex spatial morphology of urban housing prices, and has an advantage in visualizing the analysis results.
摘要：
Economic growth and eco-environmental protection are largely incompatible in the optimization of the urban land-use structure (ULUS) in rapidly developing regions. Here, we attempted to construct a model for optimizing ULUS with the inclusion of uncertain interval values, simultaneously considering the economic growth and eco-environmental protection in rapidly developing regions so as to estimate the elastic interval value of ULUS. The corresponding urban economic and environmental benefits were analyzed. Furthermore, an empirical study of Wuhan city revealed that there are certain counterbalance relationships among commercial land, industrial land and green land: the area of residential land, green land and public land is increasing year by year, and that of industrial land remains basically unchanged, while that of commercial land is decreasing gradually. Therefore, in rapidly developing regions, greater economic benefits from the ULUS are usually obtained at the cost of environmental and ecological benefits.

摘要：
Noise pollution poses negative impacts on public health particularly for urban dwellers as the land use of cities is prone to producing more road traffic and various human activities. Among the existing literature, the pathways linking built environment characteristics and noise level are not sufficiently addressed owing to a variety of complex factors affecting noise in urban areas. This study aims to examine the relationships of urban built environment and noise, using Pearson correlations and multiple linear regressions. Built environmental factors considered for this study consist of land cover, land use, and urban form. Results reveal a significant association between three aspects of urban built environment and noise level. In terms of land cover, forest alleviates noise effectively, while the effect of grassland on noise is far less impactful than forest. High-density and high-rise building areas (HHBA) are two contributors to noise pollution. The spatial layout of residential buildings is more effective in reducing noise level, as compared to the size of the residential lands. In terms of land use, the area proportion of business, open space with hard pavement, industrial, and residential land uses positively influence noise level. In terms of urban form, controlling building density is a key measure in noise reduction. Buildings with larger site coverage and complex shapes are effective in noise reduction. Findings from this study would be very helpful to formulate and implement effective measures for noise pollution mitigation, and ensure sustainable development of urban environment.
