本文以我国政府投资效率的实证研究为主线,运用DEA技术和Tobit面板模型研究1978-2014年我国28个省的政府投资产出效率、影响政府投资效率的主要因素和“四万亿”投资对我国不同地区政府投资效率的影响程度,得出结论:三大地区政府投资的效率差距仍较显著;政府投资效率与该地区的受教育程度、人口密度及对外开放程度正相关,与政府规模负相关;“四万亿”投资计划对不同地区的影响程度不同,对东部地区的正面影响高于中西部地区。
Based on the empirical research of government investment efficiency in our country, this paper studies the efficiency of government investment in 28 provinces from 1978 to 2014 using DEA technology and Tobit panel model. The main factors affecting the efficiency of government investment and the “4 trillion” The impact of investment on the efficiency of government investment in different regions of China concludes that the efficiency gap between government investment in the three regions is still significant. The efficiency of government investment is positively related to the level of education, population density and opening up in the region. Scale negatively correlated; “Four trillion” investment plans have different degrees of impact on different regions, and have a positive impact on the eastern regions more than those in the central and western regions.
