8 An Analysis of Deprived Demand on Local Public Goods During Urbanization
LI Cheng-yu,SHI Gui-fen,YANG Feng-feng
For public services in the process of urbanization, using the provincial panel data from 2007 to 2012, the paper empirically studies whether the urbanization is depriving residents to increase the demand for local public goods, as well as residents’ preference for public goods in the process of urbanization by constructing simultaneous equations model. The results show that: there are positive correlations between urbanization and six types of public goods, and in addition to environmental protection demand equation, impact coefficients of the other public goods demand equation are very significant; In the process of urbanization, the residents focus more on medical and health care demand, while the preference for environmental protection demand is small. The conclusion of this article provides certain policy implications for the local government to meet the residents' demands for public services at different levels and effectively in the process of urbanization.

14 The Conduction Mechanism and Influence of the Industry Multiplier Effect, Spillover Effect and Feedback Effect——An Empirical Analysis Based on the Interregional Input-output Models
SHANG Yong
The economic contacts among different regions can bring various influences, which are multiplier effect, spillover effect and feedback effect. The multiplier effect is the most important in three effects, and affect the others directly by the conduction of Leontieve inverse matrix. We verify the role and influence of conduction mechanism based on the two-regional Input-output model, the empirical result shows that the three effects decrease progressively according the distance of conduction paths, and the three effects have various characters based on the industries and regions. In two regional areas with enormous difference in economic scales, the connection of industries doesn’t show complete one-sided. With a adapt system arrangement, the trade between two regions can bring more bilateral benefit.

20 Dynamic Externalities and Regional Industrial Economic Growth——An Empirical Analysis Based on China’s Provincial Panel Data
QIN Yi-dong
This paper conducts an empirical study of the relationship between dynamic externalities and regional industrial growth based on China’s provincial industrial panel data from 28 regions between 2003 to 201. From the whole country it is found that specialization and diversity both have nonlinear effect on regional industrial growth, while local competition have no significant effect.Further analysis in the robustness check indicates that the effects of dynamic externalities on industrial economic growth depend on types of industry and the dimension of geographic location, but the role of local competition has nonlinear effect on regional industrial growth all the same.

26 Did Western Development Program Improve Carbon Green Contribution Coefficient in China’s Western Region?——An Empirical Analysis on Difference-in-Difference Method
ZHENG Jia-jia
Based on China’s 30 provincial carbon emissions panel data during 1995-2011, this paper uses Difference-in-Difference method to inspect the influence of Western Development Program and its mechanism. Empirical results show that Western Development Program increased the Carbon Green Contribution Coefficient in China’s Western Region significantly, which was also named the production efficiency of carbon. Through further investigation from double difference estimator, this paper finds that this Program promoted the Western Region’s economic development and Carbon Green Contribution Coefficient as well mainly by means of raising the marketing level, improving job opportunities and environment, developing foreign trade and so on. During this period, although people’s wages and educational level have significantly risen, these factors did not increase the production efficiency of carbon in Western Region. This may have something to do with the “by the waste into the luxury” consumption habit, the backward environmental awareness and the long transformation period from human capital to social productivity. Therefore, more attention should be paid to these components.

56 Transmission Mechanism of Production Factors Characteristics Evolution to Export Instability
LIN Si-yu,HUANG Fan-hua,XUE Ye-fei
This paper based on the theory of factor endowments and export fluctuations equilibrium, builds the three stage model, and on this basis using 36 countries builds a 24 years multinational panel data, examines the labor factor price evolution, capital factor price evolution impact on export instability. It is found that in developing countries the larger price change of labor and capital elements the export fluctuations performance more instability, in which the role of labor factor price more than capital elements. For developed countries, labor price change cannot significant influence on export instability; capital price change has a positive impact on export instability, but the impact is not obvious. This result shows that compared with developing countries, the export instability in developed countries have been out of the “factor driven”era.

62 A Multinational Comparative Study on the BRICS Financial Fragility ——A Factor Analysis
LIU Ye, HE Pei
This paper contracts an index of the BRICS’ financial fragility by the factor analysis method, based on fifteen indicators of financial fragility. Then, we use this index to carry out the multinational study on the BRICS. The empirical results show that the indexes of the BRICS are in various state, but in general tend to convergence. The trend of Brazil, Russia, India and South Africa’ financial fragility are fluctuant, while China presents a relative stable situation. The micro-markets index of Brazil, India and South Africa play a key role, but in China and Russia the financial market and macro-economy index is more important. To cope with the obstacles and risks in the process of BRICS’ cooperation, the five countries is supposed to take advantage of each other and promote the further cooperation.

86 Vertical Specialization, Industrial Structure Change and China’s Industrial Economic Growth Pattern Transformation
XIAO Yao,YANG Xiao-mei
By the use of the input-output method of measuring the level of china’s participation in international vertical specialization, and taking the contribution rate of total factor productivity to the contribution rate of the industrial total production value as the measurement index of the development way of China’s industrial economy. From two aspects-the whole, sub-sectors, the paper made a case study on the impact of China’s participation in international vertical specialization and industrial structure change on the development way of China’s industrial economy from 2001 to 2013.The results of the quantitative illustrate that, in general, the relationship between vertical specialization and China’s industrial economic growth pattern transformation takes on an inverted “U” curve significantly. The initial stage of participation in vertical specialization can be beneficial to China’s industrial economic growth pattern transformation, but the deepening of participation in vertical specialization can also restrain China’s industrial economic growth pattern transformation.

121 Influences of Administrator Characteristics on the Behaviors of AgriculturalCorporate Social Responsibility——Based on the Data from Five Provinces
ZHANG Sheng-rong
In terms of Structural Equation Modeling, the corporate social responsibilities can be divided into three parts----inner responsibility, outer responsibility and public responsibility. After a careful inspection upon the reliability and creditability of the questionnaire,the influences of administrators’ personal characteristics on the corporate social responsibility behavior have been thoroughly investigated with the methods of one-way variance analysis. The results show that administrators’education levels and attitudes to social responsibilityhave obvious influences on certain special dimensions of social responsibility;while age, gender and religious beliefs pose little influences on corporate social responsibilities.Therefore, to level up the corporate social responsibilities,it is important to put emphasis on the roles of administrators,to improve administrators’ quality and to correct administrators’attitudes towards corporate social responsibilities.

150 The Study of the Efficiency of China’sCurrent Monetary Policy Regulation——An Empirical Analysis Based on data from the Last 17 years
CHENG Gui ,WAN Jie-qiu,LI Meng
Based on quarterly data from the year 1998 to 2014, this paper adopts stochastic frontier analysis (SFA) which belongs to transcendental functions to estimate the true level of the efficiency of monetary policy. Empirical studies show that economic growth and price stability have the equal weight within the integrated variable of China's monetary policy. Compared to interest rate, money supply M2 has greater impact on the integrated target variable of monetary policy. The overall level of China's monetary policy efficiency is not high, the regulation effect of monetary policy has not been fully used, and there is a big gap between the preset objectives of the policy and the actual results. In order to improve the efficiency of monetary policy regulation in China, the policy regulation should be adjusted in the following aspects: (1) to reshape of the monetary policy framework and introduce flexible inflation targeting within the existing monetary policy framework. (2) To further promote the reform of interest rates and dredge transmission mechanism of monetary policy. (3) To deepen the reform of the RMB exchange rate formation mechanism, introducing more market-based mechanism.

155 Land Finance and the Circle Trap of Local Government Debt — Based on Motivation of Issuance and Cost of Issuance
SI Hai-ping,WEI jian,LIU Xiao-ge
The article investigated the likely cause of the local government debt crisis. We use the panel data of 439 prefecture-level cities quasi-municipal bond between 2009-2012 as proxy variables of local government funding vehicle debt, investigating the relationship among the issuance and the cost of local government funding vehicle debt and land finance. we found that the less land-transferring fees is , the more local government inclines to issue bond, the higher interest rates on government debt is, the more likely a debt crisis will appear. Further studies show that the city will issue large amounts of debt in case of increasing financial expenditure, and then the city will be at greater risk of debt repayment and facing the higher interest rates on government debt because of the less land revenue and weaker solvency. This kind of area which is lack of land revenue will roll over old debts with new borrowing on account of debt repayment requirements. In this way, the local government may fall into debt trap. Because the motivation of bond-issuing and the debt paying ability had almost no change, issue sizes lack of efficient control and hard budget constraints, limiting local government's financing and debt replacement way cannot solve the basic problems of local fiscal crisis.
