摘　　要：城市群作为推进城镇化的主体形态对中国经济高质量发展的作用不容忽视。本文使用2006-2015年京津冀、长三角、珠三角以及成渝四大国家级城市群的地级市数据,计算环境技术效率以考察经济质量,利用断点回归从双维度考察了城市群政策效应。研究发现:城市群政策显著提升了区域经济水平及转型,在保证经济稳步提升的前提下,进一步通过区域一体化、绿色发展等内在路径发挥政策效应。此外,应针对珠三角"畸重畸轻"、长三角和京津冀"稳中求进"、成渝潜力尚待释放的发展特征制定差异化政策。总体上,我国应适应城市群为主的空间形式,以交通、产业、环境等为中间渠道,形成"大城市为主,多管齐下,因地制宜"的驱动模式,进一步推动经济高质量发展。As the main form of urbanization,the role of urban agglomeration in high-quality economic development in China cannot be ignored.This paper uses the city-level data of the Beijing-Tianjin-Hebei,Yangtze River Delta,Pearl River Delta,and Chengdu-Chongqing national urban agglomerations from 2006 to 2015.The environmental technological efficiency(ETE)is calculated to explore the quality of economic quality.And we use regression discontinuity to study the effect of urban agglomeration policies on economic development from two dimensions and its internal mechanism.We find that,urban agglomeration policy has significantly improved the economic level and transformation of regional economy,on the premise of ensuring steady economic improvement,it is further found that the policy effect can be exerted through internal paths such as regional integration and green development.In addition,differentiated policies should be formulated according to the development characteristics of"deformed"in Pearl River Delta,"stable progress"in the Yangtze River Delta and Beijing-Tianjin-Hebei region,and unreleased potential in Chengdu-Chongqing region.Overall,China should adapt to the spatial layout dominated by urban agglomeration,and take transportation,industry and environment as intermediate channels,form a driving mode of"focusing on large cities and taking multi-measures in accordance with local conditions"so as to further promote high-quality economic development.
