Normative Analysis and Strategy Research on Harmonized Development of Modern Industrialization, Urbanization, Agricultural Modernization and IT Application

Targeting modernization, we should keep to the Chinese-style path of car- rying out industrialization in a new way and advancing IT application, urbanization, and agricultural modernization. In the research, the scientific concepts of IT applica- tion, urbanization, agricultural modernization and industrialization were illustrated and the interrelations were analyzed, with measures on harmonized development pro- posed based on existing problems.

Economic Transformation Capacities and Developmental Countermeasures of Coal-resource-based Counties of China

In China,the economic systems of many small-scale resource-based regions are confronted with realizing sustainable development through economic transformation. This paper,taking 37 coal-resource-based counties in China as objects,evaluates the economic transformation capacities of the counties by principal component analysis (PCA). Based on the comprehensive principal component values of >1,0–1 and <0,the economic transformation capacities of the counties are classified into strong,common and weak grades. Then,the paper proposes the developmental countermeasures according to different transformation capacities. For the counties with strong transformation capacities,it is crucial to make scientific positioning and rationally exploite resources in view of the developing characteristics and modes of those counties; as for the counties with common transformation capacities,the preparation and perfection of basic transformation conditions are still important aspects; as for the counties with weak transformation capacities,shifting from ″passive transfromation″ to ″active transformation″ in light of resources conditions is necessary.

Structural Vector Autoregressive Analysis of Monetary Policy in Thailand

This paper highlights the importance of monetary policy transmission mechanism in Thailand since the 1997 financial crisis and then undertakes an empirical investigation of Thailand monetary policy. This study makes effort to address both two aspects of monetary transmission mechanism, namely channels of monetary policy and the effect of monetary policy shocks on key macroeconomic variables. To address these issues, the paper specifies structural vector autoregressive （SVAR） models and estimates them using quarterly data from 1997q3 to 2014q4. The identification schemes used in this paper follow Kim and Roubini and Raghavan, Silvapulle, and Athanasopoulos with some modifications. The overall result is that the identifying restrictions used in the SVAR seem to appropriately identify a monetary policy shock even though the exchange rate puzzle is found. The results show that interest rate and monetary aggregate have played the dominant channels of monetary transmission mechanism in Thailand, while an exchange rate channel is decreasingly significant. In addition, Thailand economy is somewhat exposed to the foreign sector especially for the world price of oil and the U.S. monetary policy. The results also reveal the linkage and influence of U.S. monetary policy on Thailand monetary policy. The empirical findings are then used to provide Bank of Thailand （BOT） with insight into identifying the important monetary policy transmission channels. It would help the BOT to implement an effective monetary policy for achieving price stability through the appropriate monetary channels.

IDMI Analysis of Regional Low-Carbon Development Based on System Dynamic Simulation

During the decision-making process, especially in multi-disciplinary complex cases, assessment technique is needed to assist policy-makers in making the right decision. Many of such assessment techniques have been developed for policy-makers, but the inevitable subjectivity of policy-makers often becomes the main obstacle in making the right or proper policy. Interlink decision-making index （IDMI） is a newly proposed assessment method with the advantages of being simple to use and having less human interference over other methods, as it does not require a weighting process of each selection criterion. This paper implements IDMI to assist with decision-making in national or regional low-carbon development, using China as a case study. The Chinese government has annotmced its carbon emission reduction target along with other development targets by 2020. Many policy settings can be chosen in order to achieve those targets. The problem is how to determine the best setting and the means by which decision-makers can avoid subjectivity and extremes. A number of policy setting options are generated carefully by a system dynamic model under different policy scenarios. The IDMI demonstrates a perfect way to assist in selecting the ＂best＂ among all the options that can achieve the goals within the acceptable range.

Empirical Analysis on the Peasants＇ Cultivated Land Abandonment Decision-making Behaviors in Central China and the Subjective Factors of the Peasants --Jiangxi Province Is Taken as an Example

Following China＇s rapid advance the process of industrialization and urbanization, a large number of rural labor into cities, abandoned land becomes a universal phenomenon and shows an enlarge spread trend. Therefore, the food security of our country is threatened. This article will according to the farmers＇ angle of view, from the farmers owned their own labor, land and capital three aspects, uses field survey data to analyze the relationship between the situation of human capital, employment policy, farmland status and management decision, income and investment decision-making this five aspects and land reclamation. The result shows that age, education, arable area, whether the land transfer, engaged in non-agricultural sector employment time, work area, per capita income, non-agricultural income and investment has a significant impact on arable land abandonment, and reflect the development potential of the family of peasants and a tendency of development having a positive correlation with arable land abandonment, this phenomenon reflects in our nation, the rural residents are divorced from the original rural living environment and integrate into cities, a gradual process of get rid of the original way of life in the new way.

The research on China equity fund about the ability of asset allocation

The ability of fund asset allocation is an important factor of influence the fund performance. Choose stock funds, starting from the stock fund investment strategy, different investment strategies have their respective asset allocation. For fund asset allocation ability, this paper chose different performance indicators, through the method of comparison between group and group, listed stock funds of our country classification in K - W single factor ANOVA. At the same time, according to the result of test, analyze the causes affect the ability of the fund asset allocation, and gives the corresponding investment advice.
