基于投入产出模型的煤炭产业宏观经济效益分析

An Analysis of Macro-Economic Benefits of China's Coal Industry based on the Input-Output Model

本文基于投入产出理论模型,利用我国2007年和2010年投入产出表中与煤炭产业相关的数据,分别从成本效益、技术效益和资源转换效益三个方面对煤炭产业的宏观经济效益进行实证分析。研究结果表明,与2007年相比,2010年我国煤炭产业的成本效益与资源转换效益均显著提高,但技术效益却明显下降。

Based on input- output model,using the relevant data in input- output tables from 2007 to 2010,this paper analyzes the macro- economic benefits of coal industry in terms of cost benefit,technology benefit and resource conversion benefit. Results show that compared with 2007,cost benefit and resource conversion benefit both improved,but the technology benefit obviously declined in 2010.
