基于投入产出方法分析大型工程项目对社会总产出的影响

大型工程项目对社会经济有重要影响,但影响程度往往难以量化。根据大型工程项目所处行业的特点,从投入产出理论出发,对现行的投入产出表进行了相应的调整,并在此基础上构建四阶的投入产出模型,定量研究大型工程项目给社会总产出带来的影响,最后还结合长江干堤工程项目给湖北省社会总产出带来的影响进行投入产出实证分析。

An Analysis of The Impact of Large Projects on The Total Social Output Based on Input-output Method

Large projects always have important impact on the social economy.However,the impact is often difficult to quantify.According to the industry characteristics of large project, the current input-output tables is adjusted accordingly , and on the basis of previous work, A fourth-order input-output model is built to make a quantitative research of the impact of Large Projects on The Total Social Output.In the end, the Analysis of influence which Yangtze River reinforcement projects in Hubei Province give to Total social output of Hubei Province is used as an example to show how the innut-outout model woks.
