基于计量模型经济增长与财政收支关系的实证分析

财政收支与经济增长的关系一直存在争议。本文通过误差修正模型、格兰杰检验和脉冲响应函数进行实证分析，分析发现：财政收支与经济增长在长期均衡方面相关性不显著，但是在短期均衡上存在相互关系。财政收入能够促进经济的增长，经济的增长能够促进财政支出的增长，但是这种积极作用是逐渐形成，并不能迅速发生效果。为了保证财政收支效果，促进经济发展，本文提出了相关政策建议。

Study on Evaluation of Low Carbon Competitiveness of Steel Corp Based on Reducing Carbon-intangible Assets

We divided carbon-intangible assets into assets of carbon-intangible indicators and reducing carbon-intangible assets，according to the different sources of obtain carbon emissions rights.We constructed the low carbon competitiveness index under the perspective of reducing carbon-intangible assets,through literature researches.We used G1 method and entropy method to determine the weight of index,and put forward the comprehensive evaluation model of enterprise low carbon competitiveness.Finally,we used the model to make an empirical analysis of the six listed steel companies.
