Title: A perspective of speculative capital in Chinese stock market

Authors: PAN Junchang, TAO Jun
PP: 98-103
Abstract: This paper provided a profile of speculative capital in Chinese stock market based on billboard data from Eastmoney Company’s website and Wind database during 2005-2013. We found speculative capital boomed in 2006 and became stable after 2011. The amount of active speculative capital was about ￥32.2 billion, which mainly distributed in Shanghai, Shenzhen and Beijing. On average, there were ￥130 million per Securities Business Department and the largest volume was ￥2.3 billion in China International Trust and Investment Company, Beijing Three River Road Securities Sales Department. Speculative capital attemps to chase small company stocks which tradeable shares less than 1 billion, and the company’s operating performance is inconsequential.

Title: Empirical analysis on the coordinated development of the urbanization and industrialization situation in Shandong peninsula city group

Authors: LIU Ning, SHA Jinghua, MA Hongyun
PP: 84-89
Abstract: This research analyzed the relationship between urbanization and industrialization in the Shandong peninsula city group and measured the coordination development degree based on the statistical data from 2000 to 2011, using the method of international standard and standard value method. Therefore, there is a long-run equilibrium relationship between the urbanization and the industrialization of the city, and there is acceleration on one side. As a whole, the level of urbanization lags behind the level of industrialization. The degree of coordination development is the highest in Jinan and Qingdao, and the lowest degree of coordination development is Zibo and Weihai. The coordination development degree of either the overall urban agglomerations or inside the city tends to reasonable over 11 years.

Title: Research on the market failures and government intervention of farmland large scale transfer in China

Authors: ZHU Peixin, ZHANG Jian
PP: 78-83
Abstract: The paper provides a preference for government intervention to solve the scale of farmland transfer of “market failure” based on analyzing the defects of Chinese farmland large scale transfer market and increases the efficiency of farmland large scale transfer. Results show that the defects of Chinese farmland large scale transfer market include the monopoly and administration of market players, strong market risk and society risk, systems related to the market is not perfect. At the same time, local government is not valid in market construction, farmland circulation service and management, related institutional environment construction. Welfare economists believe that market failure is the main reason of government intervention. Thus, government should define the property rights of rural land, foster the main body of farmland scale transfer market, improve the relevant systems of the market environment, and strengthen supervision function.

Title: From exclusion to inclusion: on rural financial reform in China

Authors: ZHOU Li, LI Meng
PP: 71-77
Abstract: The new rural financial reform is focusing on the transformation from financial exclusive to inclusive, so building an inclusive financial system determines the direction of the reform. At present, the financial exclusion is significant in rural of China, and basic financial services have not covered all rural areas. Building an inclusive financial system means to eliminate financial exclusion and promote the equalization of basic financial services and improve the openness of the rural financial market. There are a lot of policies about the openness of the rural financial market, but debates still exit. To establish the better financial inclusion system, it should be enriching the providers in the rural financial system and promoting the reform of the regulatory system. At the same time, it should implement the classification regulation and supervision regulation, ensure the fairness and openness of rural financial market through legislation.

Title: Empirical analysis of operating efficiency of the village banks in Jiangsu province

Authors: SANG Yu, YU Chenyang, ZHANG Bing
PP: 64-70
Abstract: This paper made use of the statistics of 12 village banks in Jiangsu province between 2012 and 2013 to analyse the operating efficiencies of these banks using data envelopment analysis (DEA). We used staff number, the types of deposit and lending business and settlement business, and the expenditure of major business as input indexes, and the scale of lending and the revenue of major business as output indexes. The results showed that the operating efficiencies were polarized. The conditions of some banks were unstable. The average operating efficiency of village banks which were located in northern Jiangsu province was higher than that of village banks located in the center of this area and further higher than that of village banks located in the southern part of this province. But the gaps were narrowing. Finally, we used DEA-BCC model and DEA-SBM model to find that ignoring non-performing loan could not lead to biased estimate of operating efficiency.

Title: Analysis of the arrival time of animal disease for trans regional diffusion

Authors: LI Feng, JIN Zhen
PP: 49-57
Abstract: In this paper, according to the propagate mechanism of many animal diseases, we propose a n-patch dynamics model with population dispersal. Each patch contains several sub-patches in which individuals uniformly mix. Disease spreading among the sub-patches closely relates with the physical stations of sub-patches, while among the patches, it is closely related with the migration of infections. According to the mode in the initial stage of epidemic diseases prevalence, we give the general expression of disease arrival time with different epidemic diseases prevalence using random method. At last, rationality of model is verified through simulation, then we analyze the effect of migration and distances on the arrival time of disease and provide theoretical basis for formulating control measures.

Title: Study of transmission dynamics model of smallpox with emergency mass vaccination

Authors: SONG Tao, ZHANG Juan
PP: 37-48
Abstract: In this paper, the transmission dynamics model with emergency mass vaccination under the terrorism attack is established according to the mechanism of smallpox spread. The effect of vaccination rate on smallpox control and the asymptotic behavior are analysed and the basic reproductive number is found. Furthermore, the necessary and sufficient conditions of equilibria are obtained and the bifurcation point is exhibited. Using LaSalle invariant theory, the global asymptotical stability of the disease-free equilibrium is proved. The numerical simulation results intuitively show that the vaccination rate have influence on the smallpox epidemic.

Title: Fast image segmentation through super-pixels analysis

Authors: CHENG Zaixing, LIU Shuanglong, MA Jinwen
PP: 19-30
Abstract: In this paper, a fast image segmentation method is proposed with the help of super-pixels analysis. Specifically, the simple linear iterative clustering (SLIC) algorithm is firstly implemented on the image for a proper over-segmentation to form a set of super-pixels, and then these super-pixels are regarded as the basic nodes to construct an undirected weighted graph, and finally we utilize an adaptive spectral clustering algorithm to classify the super-pixels as well as the corresponding pixels and obtains a balanced image segmentation. It is demonstrated by the experimental results that this proposed fast image segmentation method based on super-pixels not only runs very fast but also keep a relatively good segmentation accuracy as well.

Title: Anisotropic diffusion model for image denoising with detail-preserving

Authors: YANG Yingying, HE Chuanjiang, WANG Wei
PP: 12-18
Abstract: To effectively remove the noise while keeping image features such as details, textures and weak edges, this paper proposes a new anisotropic diffusion model for image denoising based on the improved Perona-Malik model and curve evolution via level sets. The partial differential equation for the proposed model consists of an anisotropic diffusion term and adaptive image fidelity term. The anisotropic diffusion term uses the normalized variance that can remove the noise effectively, and the adaptive image fidelity term includes improved diffusion coefficient which can sharpen the edge of image and keep more details while removing the noise. Experimental results show that the proposed model not only can remove the noise effectively but also can preserve important details of images.

Title: Analysis and forecast of registered population in Wuhan city by using ARIMA model

Authors: DAI Huan, WANG Chuanmei
PP: 6-11
Abstract: In order to analyze and forecast the registered population of Wuhan city effectively, we established Wuhan city registered population model by using time series method. Selecting the 1978-2013 data of Wuhan city registered population, identifying and estimating the model parameters by Eviews software determined ARMA (4,2) was the optimum choice. After the inspection, we forecasted the 2014-2017 data of Wuhan city registered population. The results showed that the number of registered population of Wuhan city showed a declining trend, and the relevant government departments should adjust the population policy to ensure social harmony and orderly development.
