摘要
本文利用中国可采集到数据的30个省、市、自治区2000~2015年面板数据,借鉴Hansen的门槛面板模型,研究FDI分别在FDIs、ER的门槛效应下对工业用水效率的影响。研究发现:(1)FDI在FDIs的双重门槛作用下,对工业用水效率影响呈"N"型走势,但第一阶段回归不显著;FDI在ER的双重门槛作用下,对工业用水效率影响呈"U"型走势。(2)区域比较分析发现,以FDIs为门槛变量时,东中部FDIs回归系数显著,且促进工业用水效率提升;以ER为门槛变量时,中西部FDIs回归系数显著,且中部促进作用逐渐减弱,西部呈负相关。(3)其他变量回归结果显示,经济发展与工业用水效率之间呈正相关,水资源禀赋和国企比例对工业用水效率产生负影响,教育水平提高、环境规制不利于工业用水效率提高,但回归结果不显著或显著性不强。
Based on Hansen＇s threshold panel model, this paper makes use of panel data of 30 provinces in China from 2000 to 2015 to study the effect of FDI on industrial water efficiency under the threshold effect of FDIs and ER respectively. The results show that, firstly, the effect of FDI on industrial water efficiency shows N-shaped trend under the dual threshold of ER, but at the first stage regression is not significant. The effect of FDI on industrial water efficiency shows U-shaped trend under the dual threshold of ER. Secondly, the regional comparative analysis shows that the regression coefficient of FDIs in the central and eastern China is significant and the industrial water efficiency is promoted when FDIs is the threshold variable. When ER is the threshold variable, the regression coefficient of FDIs in central and western China is significant, and the promotion effect in central China is gradually weakened, while that in western China is negatively correlated. Thirdly, the regression results of other variables show that there is a positive correlation between the economic development and the industrial water efficiency. The water resources endowment and the ratio of state-owned enterprises have a negative impact on the industrial water efficiency.Higher education levels and environmental regulations are not conducive to the improvement of industrial water efficiency, but the regression results are insignificant or not significant.
