摘要: 在简要阐述乘子概念的基础上,基于社会账户体系,详细地推导了社会账户体系的产出乘子,将其分为组内影响、额外影响和组间的相互影响三部分.以甘肃省临泽县平川乡为例,详细阐述了社会账户体系的建立过程,并基于所建立的2000年简化的投入产出表和社会账户体系,对其社会账户的产出乘子进行了计算和分析,并根据分析结果对平川乡经济的发展提出了一些建议。

Abstract: The concept of the multiplier, Particularly multisectoral and multidimensional versions, still dominates much of the current literature in regional science and regional economics. Multipliers and their use in impact analysis had evolved from twenty years of experience in constructing regional economic models. Until recently, analyses have focused on the application of the social accounting matrix model at the regional level. In this paper, based on our building Pingchuan SAM, we use the SAM multipliers to help us understand more about the nature of linkages within a regional system as well as to create a more workable model for assessing the impact of external shocks. Firstly, social accounting matrix framework was set out in Pingchuan country context, and mathematical development of output multipliers was demonstrated in details. The impact of SAM multipliers was decomposed into three parts: (1) inter-group effect, contains the effects that injections into one group of accounts have on itself through interdependencies within the group;(2) intra-group effect, depicts own-direct effects, these are the effects resulting from the circular flow of income between groups of accounts;(3) extra-group effects, shows the effects that an injection into one group of accounts has upon some other group. Secondly, the social accounting matrix of Pingchuan country was presented in details, and some preminary analysis was made on the built social accounting matrix. The SAM multipliers were calculated based on former analysis. Finally, based on the construction and use of social accounting matrix, some proposals on how to improve Pingchuan country economy condition were put forward. With a viewing to improve Pingchuan country economy condition, prioritious development should be placed on stockbreedingand meatpacking industry.

Key words: social accounting matrix, multipliers, Pingchuan Country
