China has entered a new stage of rapid urbanization characterized by a critical period of transformation and in-depth development. Emphasizing people-oriented urbanization and optimizing the urbanization pattern is one of the important fields of national strategic decision at present. Using 2000 and 2010 census data, this paper analyzes the spatial characteristics, influencing factors and zoning scheme of recent China's urbanization development at county level, based on spatial analysis, multiple regression and cluster analysis. The main results are summed up as follows: (1) From 2000 to 2010, the residential population urbanization rate experienced a rapid increase and showed obvious regional difference. The average urbanization level of all counties increased by 1.3 percentage points annually. In 32% of all the counties the urbanization level increased by 1.5 percentage points annually. The urbanization level of eastern coastal, northeast, central and western China increased by 1.4, 0.5, 1.4 and 1.3 percentage points annually, respectively. (2) The urbanization pattern at county level changed little during the study period. Counties with high urbanization level are mainly distributed in the Pearl River Delta, Yangtze River Delta, Beijing-Tianjin-Hebei region, and eastern coastal region and provincial cities. Some 60% of counties can be divided into the categories of low urbanization level-high growth rate, low urbanization level-medium high growth rate, and low urbanization level-medium growth rate. And the three types of counties are mainly distributed in the central and western China. (3) Economic development, industrial structure, human capital, population agglomeration ability and geographical location influenced the spatial disparities of county urbanization significantly. (4) China's urbanization development at county level can be divided into five categories and 20 areas. In the new period, the development of urbanization should highlight the regional function, enhance the resources and environment carrying capacity, strengthen the industrial foundation, and emphasize the conservation and intensive use of resources. © 2016, Science Press.

Privacy trust directly affects the personal willingness to share data and thus influences the quality and size of the data, thus affecting the development of big data technology and industry. As China is probably the largest personal data pool and vastest application market of big data, the situation of Chinese privacy trust plays a significant role. Based on the 17 most common data collection scenarios, the following aspects have been observed through 508 questionnaires and interviews of 20 samples.To start with, there is a severe privacy trust crisis in China, both in the field of enterprise services such as online shopping and social networks, etc. and in some public services like medical care and education, etc. Besides, there are also doubts about data collected by the government since individuals refuse to offer personal information or give false information as much as possible. Some people even buy two phone numbers, one is in use, while the other is not carried around or used by them, which is only bought to be offered to data collectors. Secondly, in terms of gender, females have lower trust in enterprises and social associations than males, especially in the fields of social networks and personal consumption. However, there is no obvious difference in fields of government and public services. Females possess stronger awareness but less skilled in precautions than males. Thirdly, people between the ages of 18 and 50 are more suspicious of data collected by enterprises, while age exerts little obvious influence on the credibility of data collected by the government, social associations and public services. Older people are less aware of precautions than people at other ages. In addition, from the perspective of education background, people with higher degrees possess stronger awareness of precautions and thus lower degree of trust. Therefore, it is suggested that more education on privacy consciousness should be given, and relative laws as well as regulations need improving. Besides, innovation in privacy protection technologies should be encouraged. What is more, we need to reinforce the management of the internet industry and strictly regulate personal data collection of the government. © 2015 Zhong Wang & Qian Yu.

This study mainly aims to explore the spatio-temporal patterns and to simulate the future scenario of population change in Beijing based on the fifth and sixth census data at township level. The main contents and results were summed up as follows: (1) The resident population of Beijing increased with an average annual rate of 3.5% between 2000 and 2010, and the population increased by 0.6 million every year. Beijing was one of the megacities which were classified into the first range for their great amount of increased population. (2) There was an obvious circle structure in space. The population of inner city was almost stagnant; it had a rapid growth in the suburbs, and a high rate in the outer city. However, it had an increase only in the county seat and the key towns in the ecological conservation region of Beijing. (3) In terms of the CA/MAS scenario simulation analysis, in the spontaneous layout scenario, employment opportunities will be further agglomerated to the inner city, while population is suburbanized constantly. This will increase the city's commuter stress and aggravate the condition of city traffic block. When adjusting the parameters of employment and thus strengthening the guide policy of urban population living in working function, the problem of imbalance between industrial space and residential space in the urban internal space scale can be solved. At the same time, the formation of cluster of small towns can be promoted and urban commuter pressure can be reduced. Then comes the city's radiation and diffusion effect. The authors suggest that, in order to optimize the spatial distribution of population in Beijing, more efforts should be made to coordinate the relationship between employment and residents. An important way is to accelerate regional coordinated development, and to plan multi-centers development as groups. ©, 2014, Science Press. All right reserved.

Regional differences in the character of urbanization in China are substantial. The promotion of what has been termed "new-type urbanization" cannot, as a result of these regional differences, be expected to follow a universal approach-rather, such a development must objectively adhere to locational and category-specific principles and adopt differentiated urbanization development models. Regional categorization is often used in geography, but is rarely deployed in research addressing human and social problems relating to urbanization. In March 2014, China published the National New-type Urbanization Plan (2014-2020), which calls for the scientific and reasonable planning of "new-type urbanization," and appropriate regional categorizations are urgently needed in order to guide this reform. Responding to this challenge, this research engaged in the design of a "dominantly quantitative analysis, qualitatively supplemented" method in order to divide China into 5 main regions and 47 sub-regions in terms of new-type urbanization. The paper discusses the features and key problems of each region. This study introduces a new method for regional categorization, thereby remedying the lack of regional categorization in relation to "new-type urbanization" in China, and ultimately promoting the development of regional categorization in the humanities as a valuable reference for healthy and sustainable Chinese urbanization. © 2015 Fang et al.This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.

Identifying the problem regions and regional problems, and thus improving regional policies, are crucial for the sustainable development of various economic entities. The coordinated development of industrialization, informatization, urbanization and agricultural modernization (hereinafter referred to as “Sihua”) is not only a practical need but an important strategic direction of integrating urban-rural development and regional development in recent China, and it also provides a significant perspective for identifying problem regions and regional problems so as to improve the regional policies. This study mainly aims to: firstly, establish a comprehensive evaluation index system so as to explore the spatial pattern of coordinated development of Sihua in China at prefecture level; secondly, to develop an evaluation criteria system to identify the problem regions and regional problems from the perspective of coordinated development of Sihua. This paper comes first in the scientific community to evaluate the coordinated development state of Sihua in China at prefecture level and identify the problem regions and regional problems from the perspective of Sihua development by quantitative analysis. This study may benefit the improvement of regional policies and thus contribute to the sustainable socio-economic development of China. © 2014, Science in China Press and Springer-Verlag Berlin Heidelberg.

This paper transforms the constraints of the vehicle routing problem, analyzes the attributes of each index influencing the vehicle route and optimizes relative weights between attributes of different indexes to combine the entropy theory with the subjective weight. This will permit formation of a more objective comprehensive weight through theoretical models and entropy method mode based on the actual situation of urban transport planning. In the paper, the direct superposition approach of route optimization existing in literature is improved; through data driven analysis, this paper also linearly superposes the attribute weights of each index and randomly plans relative weights of indexes according to the priorities of each index attribute, which provides a guideline for the nonlinear superposition of indexes, applicable to superposition calculation of more dimensions index attribute. Examples in the paper will show that it can be greatly applied to the project planning and optimization of category one vehicle routing and thus paves the way for the subsequent optimization calculations. © 2015 Taylor & Francis Group, London.

Based on the basic data of the housing price and housing price-to-income ratio in 286 prefecture-level cities in 2009, this paper analyzes the spatial differentiation pattern, overall trend, spatial heterogeneity and correlation between the absolute housing price and relative housing price. The results show that: 1) there is significant spatial differentiation in terms of China's urban housing price, and the distribution presentsdual patterns of spatial clustering differentiation (the three southeast coast urban agglomerationsversusinland cities) and administrative level differentiation (between provincial capital and prefecture-level cities). 2) The overall differentiation trend and spatial heterogeneity of absolute housing price are higher than that of the relative housing price. © 2013 IEEE.

This paper uses the Global Trade Analysis Project (version 7) database to calculate embodied CO2 emissions in bilateral trade between China and other countries (regions) based on input-output methods. The sources and flows of embodied CO2 emissions in import and export trade of China are analyzed. Results show that the flows of embodied CO2 emissions in export trade are highly concentrated. The main flows to the United States (US) and Japan account for 1/4 and 1/7 of the total CO2 emissions in export trade, respectively. Concentrated flows of total exports and small differences in export structure are the main reasons for the highly concentrated export trade. The sources of embodied CO2 emissions in import trade have relatively low concentration. Taiwan Province of China, Hong Kong Special Administrative Region of China, US, Russia, Republic of Korea, and Japan account for around 7.72%-12.67% of the total embodied CO2 emissions in import trade. The relative dispersion of import sources, the impact of the import structure, and the level of production technology in importing countries caused low concentration of CO2 emissions in import trade. Overall, the embodied CO2 emissions in the export trade of China are higher than those in import trade. As a result, production-based CO2 emissions are higher than consumption-based CO2 emissions. The difference of 8.96 × 108 t of CO2, which comes mainly from the US, Japan, Germany, and the United Kingdom, accounts for 58.70% of the total difference. Some suggestions, such as improving energy efficiency, alerting high carbon-intensive industries transfer, expanding the market for sharing risks, and prompting the accounting system of consumption-based CO 2 emissions, are proposed based on the results. © 2014 Science Press, Northeast Institute of Geography and Agricultural Ecology, CAS and Springer-Verlag Berlin Heidelberg.
