| 摘要: |
| 以2006—2015年中国274个地级市的面板数据为基础,实证分析制造业集聚对城市绿色全要素生产率影响的门槛效应。研究发现,全样本下制造业集聚与绿色全要素生产率之间呈倒“N”型关系。考虑城市级别和城市规模后,不同类型城市的制造业集聚门槛效应存在差异。高级别城市中,随着制造业的不断聚集,制造业集聚对绿色全要素生产率的促进作用逐渐减小,并最终变为负向;一般城市中,制造业集聚跨越门槛值以后,对绿色全要素生产率的不利影响将明显减弱;小城市只要迈过第一个门槛值就可以发挥制造业集聚对绿色全要素生产率的正向作用。环境规制、科技投入以及经济发展水平都对城市绿色全要素生产率有积极影响。 |

| Abstract: |
| The threshold effect of manufacturing agglomeration on cities green total factor productivity is analyzed empirically by using panel data of 274 cities from 2006 to 2015. There is an inverted N-type relationship between manufacturing agglomeration and green total factor productivity under the whole sample. In consideration of the administrative level and the size of the city, the manufacturing agglomeration threshold effect varies among different types of cities. For a city with a high level of administration, the accelerating effect of manufacturing agglomeration on green total factor productivity gradually decreases with the continuous accumulation of manufacturing industries, and eventually becomes negative. For general cities, after manufacturing agglomeration crosses the only threshold, its adverse impact on green total factor productivity will be significantly reduced. For small cities, manufacturing agglomeration can exert the positive effect on green total factor productivity as long as the first threshold is crossed. In addition, environmental regulation, scientific and technological inputs, and economic development levels all have a positive impact on citiesgreen total factor productivity. |
