A study of virtual land trade between China and ASEAN based on material flow analysis model

In this paper,based on the material flux analysis model（MFA） and its corresponding theories and algorithms of ＂virtual land＂ virtual land contents of five primary agricultural products are calculated and＂Virtual land trade＂hidden in those imported and exported products are also obtained through analyzing the primary agricultural product trade between China and ASEAN. In the process of calculationl following the thought of Changing agricultural products to ＂Virtual land trade＂land content, trade condition and spatiai distribution of agricultural products Were integratedly considered. indicate that China exported 73;057 km^2 of virtual land area to ASEAN by tea, vegetables; maize and grain, ASEAN exported： 57.332 km^2 to China by natural rubber from 2002 to 2005. It obvious; that china has lost 15,725 km^2 arable land through agricultural product trade, Additionally, in order to process： of calculation Virtual land trade, Thailand taker as an example to analyze its international trade of rice and Wheat from 1991 to 2005 and Calculate their ＂Virtual land trade＂ 2001 through 2005. According to and calculation, it is not difficult to conclude that ＂Virtual land trade＂ very important and could be used for China to guide agricultural export or import Structure and maintain Sustainable use of land resources.     

Electoral information in developed stock market: testing conditional heteroscedasticity in the market model

By about 1988, the consensus among leading health economists was that no meaningful differences existed among hospitals of differences owernership form, and this position was embraced by the Antitrust Division of the US Department of Justice. But behavioural differences among hospitals of different among hospitals of different owernership has continued to be a matter of both academic and judicial interest. Recent empirical studies have concluded that real differences do exist, while many earlier studies reached the opposite conclusion. This contradiction in finding over time, as competition intensified, is exactly opposite to what expense-preference theory would predict. We examine this apparent paradox, using a very general test of behavioural differences by hospital ownership. We find that the omission of location-specific variables can lead to biased estimates of ownership effects, and that no significant behavioural differences exist among private California hospitals in 1986–90, when this source of ownership endogeneity is eliminated.     

中国城市间流通网络及其层级结构——基于中国连锁企业百强店铺分布的网络分析

本文以网络的视角透析中国城市间的流通体系,选取中国连锁百强企业的店铺网络为样本,应用社会网络分析的测度方法,对中国城市间流通网络的整体属性及其层级结构进行了研究.研究发现:(1)联结全国主要城市的完整流通网络已初步形成,但网络密度不高,并且网络区域性特征明显,区域网络之间存在重叠,也存在结构洞.(2)中国城市间流通网络的不均衡性较强,层级结构明显,北京和上海是城市间流通网络的核心.(3)流通网络在空间分布上很不均衡,也呈现明显的层级结构,东部地区的网络密度明显高于中、西部地区,东部城市在网络层级中的位置较高,而网络结构洞主要存在于中、西部地区和东部地区之间.

市场型交易关系的建立与发展及其运行机制

本文以辽宁普兰店蔬菜流通渠道为案例,全面考察了蔬菜流通渠道中市场型交易关系的建立、发展与终止过程,重点考察了在交易关系发展各个阶段重要的互动行为如何影响了交易关系的发展,并建构了市场型交易关系建立与发展过程的概念模型。研究发现市场型交易关系是在市场价格机制和农村人际关系要素这双重机制影响下的交易关系,这种双重制约机制不仅使得此类交易关系具有一些市场交易的特征,同时还具有长期导向性的内在稳定机制。
