摘　　要：利用2004—2015年中国249个地级以上城市的面板数据,采用系统广义矩估计方法和面板门槛模型,研究了金融集聚对城市绿色经济效率的影响,得出以下结论:金融集聚能够提升城市绿色经济效率,具体体现在增强技术创新、优化产业结构和实现节能减排三种渠道;当金融集聚水平跨越不同门槛时,金融集聚对城市绿色经济效率的提升作用会发生变化,从全国以及中、西部地区的情况来看,金融集聚与城市绿色经济效率之间存在U形非线性关系,而在东部地区两者之间存在提升作用逐步递减的非线性关系。Using the urban panel data of 249 cities at the level of municipality or above in the period of 2004-2015,this paper adopts the system GMM method and the panel threshold model to study the influence of financial agglomeration on green economic efficiency of city in China.The conclusions are as follow:financial agglomeration could enhance green economic efficiency of city,which embodies in three channels,namely strengthening technological innovation,optimizing industrial structure and realizing energy saving and emission reduction;when the level of financial agglomeration crosses different thresholds,its role in promoting green economic efficiency of city will change;there is the U-shaped nonlinear relationship between financial agglomeration and green economic efficiency of city in middle and west regions;the nonlinear relationship between them takes on a trend of declining gradually in east region.

关 键 词：金融集聚 城市绿色经济效率 系统广义矩估计 门槛效应
