Economic Analysis of the Financial Supporting Policy in the Economic Development Zones

This paper makes an economic analysis of the Financial Supporting Policy to invite outside investments in the Economic Development Zones(EDZs),deduces the formula of the optimal ratio of the quantity of financial support to the local financial income and draws figures of the curve.The EDZs should consider the effectiveness of financial subsidy before they use this policy;technical progress is the precondition of subsidy.The Financial Supporting Policy should first help those industries that can promote local economic growth best get subsidy.Under the conditions of low initial economic level and subsidy combining with other preferred policies,the ratio of financial subsidy should reduce;properly by prolonging the time limit and the EDZs' paying more attention to long-run objection lead to lower subsidy ratio.

Regional Economic Diversity and Diversification

ABSTRACT Regional scientists have long attempted to develop meaningful definitions and measures of economic diversity and diversification, and to establish functional relationships between diversity, diversification, and economic performance. The multiplicity of definitions and measures explains, in part, the confusion about these relationships. A framework that sorts out the overlaps, contradictions, and gaps of the various definitions and measures IS needed. Such a framework would explicitly address the question, “What is the relationship between a region's changing economic structure and performance?” In this paper it is suggested that an input-output model that incorporates elements of portfolio theory be used as the integrating framework for analysis.     

水稻产业经济问题的研究

本文在分析我国粮食及水稻生产现状的基础上,针对农业进入新的发展阶段后因稻谷结构性过剩、市场粮价低迷而出现的忽视水稻生产的倾向。提出了“水稻产业经济”概念,并对其属性、内涵、要素等方面进行了阐述,确立了发展“水稻产业经济”的基本思路和应采取的“区域化布局”等一系列战略措施,对促进水稻产业的持续、协调、稳定发展具有重要的意义。……     

兰州-白银经济区高新技术产业集聚与区域经济增长关系的实证分析

以兰州-白银经济区的高新技术产业为研究对象,依据2000—2011年的时间序列数据,采用区位熵指数对高新技术产业的集聚水平进行测度,并在此基础上,对高新技术产业的集聚与经济增长的关系进行协整及格兰杰因果检验,进而构造VAR模型并得到脉冲响应函数。实证结果表明：兰白经济区的高新技术产业已经形成了集聚且集聚度呈稳定增长的趋势,同时,高新技术产业的集聚与经济增长之间存在长期的均衡关系。最后分析得出兰白经济区的高新技术产业集聚是一种政府主导型的集聚模式,并提出了相应的政策建议。     

Economic Stability and Economic Growth in Rural Communities: Dimensions Relevant to Local Employment Creation Strategy

Approaches for analyzing employment stability with aggregated data for SICs in large regions or major metropolitan areas are misleading indicators of the impact of manufacturing growth in rural areas. Performance of moderate-sized individual establishments seriously impact total employment variation in small-employment-sized rural communities, requiring analysis of the determinants of employment stability of these establishments. Aggregate SIC performance and most conventional criteria for judging probable stability appear to provide very limited predictability for individual firm performance. However, manufacturing development appears generally to have desirable effects on community-wide employment stability.

植物经济谱研究进展：综述

以叶和根经济谱为基础,分析了植物经济谱,并进一步探讨了植物经济谱地上、地下的相关性,同时对其相关性研究进行了评价。基于现有研究成果,笔者针对叶寿命、比叶面积、光合速率、呼吸速率以及氮和磷含量共变,详细阐述了叶经济谱;针对根直径、根干物质含量、比根长、氮和碳含量、水溶性化合物、纤维素和木质素浓度共变,详细阐述了根经济谱。同时,通过对功能性状共变的解析,得出地上、地下部分植物经济谱的相关性。为更好地认知植物经济谱,笔者提出如下建议：增加研究植物经济谱的物种和群落,对全部植物功能性状参数进行分析整合,建立全球植物经济谱模型,探讨环境因子对植物经济谱的影响。对植物经济谱的详细分析和探讨,可为这一新研究方向提供技术支持。     

Economic heterogeneity within large metropolitan areas

In recent years, research has indicated a trend in the US for the distribution of income to become bimodal, with movement away from a dominant middle class and toward more people being in the upper or lower ends of the income scale. With this trend, an analysis of municipalities would be expected to show frequency distributions for various economic variables that would have widened, become more skewed, and become flattened or U-shaped. Additionally, the mode of distribution would be expected to move toward the lower income end. An analysis of individuals within the rich and poor communities would be expected to show frequency distributions that have narrowed. This study tested the above expectations. The usual measures of skewness and peakedness were used for data analyses, as well as a modified Pearson place. The metropolitan areas sampled were Atlanta, Boston, Chicago, Dallas, Detroit, Los Angles, and Washington, DC. Changes were looked for in comparing per capita income figures from the US Census for each municipality in the metropolitan areas in 1969,1979, and 1983. For individual municipalities, a sample of 30 Chicago suburbs was used to show income distribution. Results of per capita income in metropolitan areas (except Dallas) for 1969-1979 showed that middle income communities became more dominant, not less; therefore, the poorer communities became richer. The results for 1979-1983 showed that the trend came to a halt. For individual income results, a trend toward greater homogeneity in the 1970s came to a halt in the 1980s and began to reverse itself. For individual municipalities, the larger ones were more heterogeneous. Additionally, those with greater population increases were more homogeneous in income, and those with the highest increases in income tended to be moving toward more homogeneity. The poor communities, therefore, were more income-heterogeneous. A bimodal income distribution does not exist, but some metropolitan areas are moving in that direction.
