| 摘 要： | 基于省际水足迹和灰色水足迹等的面板数据，论文利用带有“非期望”产出的数据包络分析方法测度了1997-2010 年中国31 个省市区的水资源全局环境技术效率，并与未考虑“非期望”产出的数据包络分析方法测度水资源技术效率进行了对比；运用空间计量模型研究了考虑“非期望”产出的中国省际水资源全局环境技术效率和未考虑“非期望”产出的技术效率的空间效应。研究发现这两种情况下的中国省际水资源技术效率都具有显著的空间自相关性；通过LM检验和稳健LM检验，中国省际水资源技术效率存在空间依赖性和异质性，借助于空间滞后模型和空间误差模型进一步研究，发现中国省际水资源全局环境技术效率和技术效率的主要影响因素及其影响方向存在很大差异，考虑“非期望”产出的全局环境技术效率是对中国水资源利用效率一种科学合理的测度，而未考虑“非期望”产出的技术效率测度存在误导和偏差。在此基础上对中国水资源利用效率健康发展提出了相应的政策建议。 |

| Abstract: | Water resources use efficiency DEA model for the measurement of China water resources use efficiency exists some deficiency. In the investment, it is simple to take the water for daily life and production indicators together with other indicators as inputs. These inputs did not reflect water resources consumption of the real socio-economic system. In the undesirable output, it is pure to consider the water pollutant of COD and nitrogen ammonia emissions as the expected output, but not considering the real loss caused by the water pollution to water environment. This neglect must have an effect on the evaluation results of the water resources use efficiency. There is no space effect hypothesis on the research of the influencing factors about China's water resources use efficiency. And implying ordinary least squares (OLS) of ignoring space effect makes the model to estimate. In practical application there often exists deviation problem in the model set, which leads to the problems that are not complete and scientific, due to lack of explanatory power on the influencing factor analyses results and inference of China water resources use efficiency. According to the shortage of the above and based on the panel data about interprovincial water footprint and grey footprint and other data, this paper measures water resources Global Environmental Technology Efficiency (GETE) of 1997-2010 China's 31 provinces by using an "unexpected" output DEA method, and studies the space effect of interprovincial water resources GETE with the help of the space measurement model. The empirical results show that the interprovincial water resources GETE is significantly correlated in space. Through the LM test and robust LM test, the China's interprovincial water resources GETE exists spatial dependence and spatial heterogeneity, then by means of spatial lag model and the spatial error model this paper further found that China's interprovincial water resources GETE has strong spatial spillover effect. Spatial autoregressive coefficient and space error coefficient respectively are 0.5280 and 0.7480 under considering the unexpected output by 1% significance level. The influencing factors and direction of Chinese interprovincial water resources GETE and TE differ from each other. The water resources GETE considering the unexpected output is a scientific and reasonable measure. On that basis, this paper puts forward relevant policy suggestions for healthy development of China's water resources use efficiency. |
