The development of the wind energy sector is often promoted as a means of supporting rural economies. This paper focuses on how the ownership structure of on‐shore wind power plants (external, farmer or community) affects the size and distribution of impacts within the rural part of a region. Empirical analysis is based on a regional computable general equilibrium model of North East Scotland with the results compared to those generated from a standard social accounting matrix multiplier analysis. With no local ownership, while rural GDP increases, there is almost no effect on household incomes due to the limited direct linkages of the on‐shore wind sector. Local ownership increases the household income benefits but there are still limited positive spill‐over effects on the wider economy unless factor income is re‐invested in local capital. With re‐investment, farm household ownership gives rise to the largest increase in total household income but community ownership gives rise to the largest increase in rural (non‐farm) household incomes and welfare. The results contribute to the on‐going debate about the opportunity cost of external asset ownership in rural areas.  相似文献

In general terms, key sectors analysis aims at identifying and quantifying the economic impact of a sector in a given economy. For a sector, we mean here either an industry or a region, or even a cluster of them. Quite a few measures and methodologies of varied complexity have been proposed in the literature, from multiplier sums to extraction methods, but not without debate about their properties and information content. All of them, to our knowledge, focus exclusively on the interdependence effects that result from an input–output structure of the economy. By so doing the approach misses critical links beyond the interindustry ones. A productive sector's role is that of producing but also that of generating and distributing income among primary factors and households as a result of production. Thus, when measuring a sector's role, the income generating process should not be omitted if we want to elucidate the sector's true economic impact. A simple way to make the missing income links explicit is to use the SAM (Social Accounting Matrix) facility. Extending an extraction methodology to the SAM we compare lost output with and without the missing links. We observe that substantial differences in sectoral lost gross output arise but, even more important, we capture the implied shifting in the rank ordering of sectors.  相似文献

This article develops a method for establishing water prices and their effects in order to provide policy makers an environmentally and socially optimal range of regional prices for irrigation water. Two prices are determined. The “environmentally optimal price” of water is defined as the one that internalizes the environmental costs generated by agricultural consumption. The “social optimally price” of water is defined as the one that maximizes levies on water for agriculture without affecting the regional economy. The environmentally optimal price is calculated with an economic model built over a Geographical Information System (GIS) that allows the economic quantification and valuation of the environmental cost of water in different basins. The optimal price is calculated with a demand curve for irrigation water introduced into a Social Accounting Matrix (SAM) to observe if the regional economy can accept higher prices without affecting the regional GDP. Potential water prices are established, ranging from prices that minimize the negative impact in the regional economy to those that totally internalize the environmental cost of water.  相似文献

随着世界经济一体化和空间经济学的日益发展,系统模型方法在国家或区域间经济联动方面的扩展和深化研究正在显现出巨大的应用价值。本文首先开发一个世界连接可计算一般均衡模型,科学揭示各经济体的运行特征,为定量剖析世界范围内各经济体的经济增长、结构变动方面提供一个系统分析框架:一方面在模型的理论框架中,分析了世界CGE模型各个模块的构建思想和对应的主要方程及其特征;另一方面建立了世界连接社会核算矩阵。然后通过动态模拟分析,检验链接模式和国家间经济联系,以及应用于各经济体政策变化的综合影响评价。  相似文献

根据中国2007年的社会核算矩阵(SAM)表,利用基于SAM的乘数和相对乘数方法,分析中国各部门收入分配和再分配的结构效应,结果表明:当外生注入行业部门时,大部分行业之间的分配和再分配影响是非相互促进的,行业部门对城乡高等阶层的初始分配比较有利,对城乡中等阶层的再分配较有利;当外生注入居民部门时,各阶层居民之间以及居民对生产部门的分配和再分配的影响也是非相互促进的;当外生注入政府部门时,政府对各行业的分配和再分配的影响是不对称的,不利于高等阶层但却比较有利于低等阶层的分配和再分配。  相似文献

层次分析法在战略对应模型中的应用研究   总被引:4,自引:0,他引:4  
层次分析法AHP(Analytic Hierarchy Process)是70年代末期美国运筹学家Saaty提出的一种定性与定量分析相结合的决策分析方法,由于它能够把决策者的主观判断和推理紧密地联系起来,对决策者的推理过程进行量化描述,因此,它在结构较为复杂,决策准则较多且不易量化的决策问题中得到了广泛应用。  相似文献

文中从电信运营商采购管理的全局出发,提出并构建了采购管理系统优化的概念框架,在此基础上分析了采购管理系统的构成、管理层次的划分、采购职能的分配,以及采购工作的具体流程。以集中化、精细化管理为指导原则,文中认为采购管理包括四方面核心内容,即供应商准入管理(SAM)、供应商选择管理(SSM)、供应商关系管理(SRM)和供应商监控管理(SMM)。建议电信运营商采购管理部门除应重视招标采购职能建设外,还应强化供应商准入管理、供应商关系管理和供应商监控管理三个管理职能,在采购流程中应增加供应商资源库的建设,中标供应商的分类管理,以及奖惩机制的建立等。  相似文献

This paper provides the latest Social Accounting Matrix (SAM) of the year 2003–2004 for the Indian economy with a wide variety of disaggregation for the Energy sector and the sectors that are relevant for environmental and climate policy evaluation. This SAM shows the interaction between production, income, consumption and capital accumulation. It can be used to provide an analysis of the interrelationship between the production structure of an economy and the distribution of incomes and expenditures of different household groups. In addition, it can be used for multiplier analysis to capture direct, indirect and induced impact on input use due to any exogenous changes in the economy. This SAM consists of 85 sectors of the economy, three factors of production and nine categories of occupational households. The Indian economy is becoming structurally biased towards capital intensive sectors, such as service and energy production. The energy production sector itself is the most energy intensive sector as of 2003–2004.  相似文献

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。  相似文献
