摘要
基于2003-2016年中国省际面板数据,采用SBM方向性距离函数和ML指数测算中国绿色全要素生产率,并构建面板门槛模型实证检验交通基础设施对绿色全要素生产率的非线性影响。结果显示:在样本考察期内,我国绿色全要素生产率的增长幅度呈东中西的顺序依次递减;全样本下,交通基础设施对绿色全要素生产率的影响存在单门槛效应,当交通基础设施固定资本存量低于门槛值时,它会促进绿色全要素生产率的提高,一旦超过门槛值,则会抑制绿色全要素生产率的增长;分样本下,中部、西部地区存在单门槛效应,东部地区则不存在门槛效应。
Based on the 2003-2016 Chinese provincial panel data, the SBM directional distance function and ML index are used to measure China’s green total factor productivity, and the panel threshold model is constructed to empirically test the non-linear impact of traffic infrastructure on green total factor productivity. The results show that during the sample study period, the growth rate of China’s green total factor productivity is decreasing in the order of east, middle and west. The impact of traffic infrastructure on green total factor productivity under the whole sample has a single threshold effect, when the transportation infrastructure is below the threshold, it promotes the increase in green total factor productivity, and once it exceeds the threshold, it will inhibit the growth of green total factor productivity. There is a single threshold effect in the central and western regions under the sample, and there is no threshold effect in the eastern region.
