我国超大城市碳排放与经济增长关系的实证研究

城市经济发展离不开能源消费，而能源消费直接导致大量的碳排放，深入研究碳排放与经济增长之间关系对超大城市实施节能减排、发展低碳经济具有重要意义。本文分别选取了上海市、北京市、天津市和重庆市1995～2014年碳排放和经济增长的相关数据，对两者的脱钩关系和格兰杰因果关系进行实证研究，得出长期内实施碳减排政策不会阻碍超大城市经济增长的结论。因此，超大城市应该积极推动低碳城市建设，不断推动产业结构升级，改善能源消费结构，积极实施节能减排政策和倡导低碳生活。

The Empi rical Study on the Relationship between Carbon Emissions and Economic Growth in Megacity Behemoths

〔Abstract〕 The development of city economy depends on huge exhaustion of energy , but it can directly lead to the increase of carbon emissions . The empirical study on the relationship between carbon emissions and economic growth is of great significance for megacity behe-moths to implement energy conservation and emissions reduction , development of low carbon economy . This paper selects the Shanghai-Beijing-Tianjin-Chongqing data on carbon emissions and economic growth from 1995 to 2014 , to study their decoupling relations and granger causality . It is concluded that implementation of carbon reduction policy will not hinder economic growth of the megacity behemoths in the long term . Therefore , megacity behemoths should actively promote low-carbon urban construction , constantly promote the upgrad-ing of industrial structure , improve energy consumption structure , active implementation of energy conservation and emissions reduction policy and advocate low carbon life .
