An Evaluation of Institutional Matrices Theory Which Was Designed to Illustrate Differences Between Russian and Western Political Economies

This article is devoted to the evaluation of the institutional matrices theory (IMT), which was designed to illustrate the differences between Russian and Western political economic systems. IMT has no matrix, and it is an ideological declaration rather than a theory. It is a set of assertions and assumptions that are adopted without evidence, and then hypostatized to be Russian and Western socioeconomic systems. IMT literature claims to utilize the reciprocity, redistribution, and exchange model of Karl Polanyi (1944 Polanyi, Karl. The Great Transformation. New York, NY: Rinehart &; Company, 1944. [Google Scholar], 1957 Polanyi, Karl. “The Economy as Instituted Process.” In Trade and Market in the Early Empires: Economies in History and Theory, edited by Karl Polanyi, Conrad M. Arensberg and Harry W. Pearson, pp. 239-270. New York, NY: Free Press, 1957. [Google Scholar]). However, IMT suffers from a number of assumptive and methodological problems in its application, the first of which consists of the complete exclusion of reciprocity from consideration. The first section of the article is an explanation of problems with IMT, and the second section demonstrates some particulars of the IMT problems with a real-world social fabric matrix from a Western nation.

人民币实际汇率升值对中国经济各产业的影响——基于可计算一般均衡模型(CGE)的分析

研究构建了一个可计算一般均衡模型(CGE)以量化估算人民币实际汇率升值对中国经济各部门的影响。根据最新的中国2005年投入产出表编制了中国2005年社会核算矩阵作为CGE模型的基础数据集。研究表明:除服务业、建筑业外,人民币实际汇率升值使大部分产业产出下降,升值的财富效应导致国内购买力增强,服务业、建筑业产出随之增加;升值使农业部门的农业劳动力需求减少,服务业、建筑业的劳动力需求增加,大部分非农行业的劳动力需求也都趋于减少。     

国有纺织服装外贸企业应对“后配额时代”的SWOT分析

国有纺织服装外贸企业曾经是中国纺织服装出口的主力军。随着“后配额时代”的到来,国有纺织服装外贸企业的生存、发展环境发生了重大变化。运用SWOT方法,深入分析国有纺织服装外贸企业的内外部环境,得出以下结论：在其企业内部环境中,行业经验、人力资源、管理和资金等方面具有一定优势,但在新产品开发及创新能力、产品科技含量、自主品牌创建等方面存在劣势;而在其外部环境中,存在外部机会的同时也要面临诸多威胁。为此,国有纺织服装外贸企业应通过制定S0战略、WO战略等有效的经营战略来应时“后配额时代”的竞争。

AN APPLICATION OF AN INTEGRATED TRANSPORT NETWORK – MULTIREGIONAL CGE MODEL TO THE CALIBRATION OF SYNERGY EFFECTS OF HIGHWAY INVESTMENTS

A transportation network-multiregional CGE model is applied to estimate the synergy effects of a set of highway projects on value added by region and industrial sector. This synergy effect is defined as a difference between the summation of the net GDP increase from the development of each highway sub-link without spatial linkage and the change in GDP resulting from the concurrent development of all links with spatial linkages. Among nine east–west highways in Korea, the East–West 9 highway increases the GDP by 0.3% over the 30-year time period horizon, with 0.016% of the GDP due to the synergy effect. The East–West 9 highway has the largest synergy effect of US$0.164 billion per year on the manufacturing sector of Kwangju Metropolitan Area, resulting in a gain in a regional GRP per capita of US$15.88 per year. Since most synergy effects are generated in less developed regions, highway development can contribute to the reduction in regional disparities.     

Observational evaluation of outcomes and resource utilization from hemostatic matrices in spine surgery

Abstract

Objective:

Studies have indicated that outcomes may differ by choice of flowable hemostat, but there is limited evidence in spine surgery. The objective of this study was to conduct a comparison of outcomes following use of advanced flowable hemostatic matrices in a large spine surgery population.
