劳动力价格扭曲与绿色经济效率损失

Labor Price Distortion and the Loss of Green Economic Efficiency

基于中国30个省份2000—2016年的平衡面板数据,分别采用超越对数生产函数模型和包含非期望产出的SBM超效率模型对各地区的劳动力价格扭曲和绿色经济效率进行测度,并使用两步差分GMM实证检验了二者的关系。研究发现:劳动力价格扭曲程度总体表现为负向扭曲并呈不断恶化趋势,东部地区的绿色经济效率明显高于中西部地区;劳动力价格扭曲在2000—2016年以及2009—2016年均显著抑制了绿色经济效率的提升,但这种抑制效应在2000—2008年表现并不显著,总体上通过消除劳动力价格扭曲可使全国的绿色经济效率提升约7.12%;公共交通基础设施、外商直接投资、产业结构和国有企业比重的提升均对绿色经济效率有显著促进作用,而对外开放程度则显著降低了绿色经济效率。

Based on the balance panel data of 30 provinces in China from 2000 to 2016,the article tests the labor price distortion and the green economic efficiency of different regions by using the transcendental logarithmic production function model and the SBM super-efficiency model with undesired outputs,and the relationship between the them is empirically tested by using two-step differential GMM.The study finds that the overall distortion of labor price is negatively distorted and shows a deteriorating trend.The green economy efficiency in the eastern region is significantly higher than that in the central and western regions.Labor price distortions from 2000 to 2016 and 2009 to 2016 have significantly inhibited the green economic efficiency,but this suppression effect was not significant from 2000 to 2008.By eliminating labor price distortions,the overall green economic efficiency of China will increase by about 7.12%.The proportion improvement of public transportation infrastructure,foreign direct investment,industrial structure and state-owned enterprises can significantly improve the green economic efficiency,while the degree of reform and opening has significantly reduced the green economic efficiency.
