我国水利投资效率演进的时空特征及影响因素——基于空间计量的视角

Spatio-temporal features and influencing factors of investment efficiency of water conservancy in China: perspective based on spatial econometrics

在全要素生产率的视角下,测算我国2008—2012年30个省(直辖市)的水利投资效率,从动态演进的视角描述我国水利投资效率空间分布及其演化特征。在此基础上,运用空间计量方法分析影响我国水利投资效率的因素。结果表明,我国水利投资效率演进呈现出极化效应,在空间分布上呈现出显著的依赖性。第一产业产值、财政收入是影响水利投资的主要因素。研究结论为政府宏观管理提供政策建议,有效促进水利建设健康发展。

The investment efficiency of water conservancy in 30 administrative regions of China is calculated from the perspective of total-factor productivity by using the data from 2008 to 2012.The spatial distribution and evolution features of the investment efficiency of regional water conservancy are analyzed through the spatial autocorrelation analysis.On this basis,the influence factors for the investment efficiency of water conservancy in China are investigated by means of the spatial econometrics.The results show that the investment efficiency of regional water conservancy in China exhibits a polarization effect and a tendency of spatial dependence.The output of the first industry and the fiscal revenue are the main factors affecting the water conservancy investment.The research may provide some suggestions for the macroscopic management policies so as to effectively promote the healthy development of water conservancy in China.
