As a worldwide integration of interests in ecology,economy and politics,Low-carbon economy has become an important strategy in many countries and regions. To achieve the goal of acting as a responsible country, China is now striving for a low-carbon development and sustainable development.This paper firstly summarized the progresses in low-carbon research,which include:background,conception,theory basis,etc. There were five basic connotations in understanding and definition of low-carbon economy,according to the provisions of the article.It proposed a study framework of development strategy of low-carbon economy,which include carbon politics and carbon emission rights distribution,objective strategies, indicator system and carbon emission estimation methods.Then,it introduced some progresses in domestics and aboard in the research of the development strategy of low-carbon economy from several aspects such as policy paths,policy tools,policy simulations,etc.Finally,this paper pointed out the inadequacies of the current study on low-carbon economy, and gave out several prospects for further study.Several trends and basic contents of domestic researches should be improved:(1)Further study of the theory of low-carbon economy,Such as theoretical basis,methodology and evaluation index system.(2)Study on the development strategy and policy tools of low-carbon economy. It is required to draw up a series of strategies from different perspectives of social economy and complete sets of policy tools in many ways.(3)Study on regional development modes.The target，such as total and subunit，comprehensive planning and route map with Chinese characteristics are drew up in order to make strategies of low-carbon development.(4)Development potential, market size, economic and technical risks analysis.The key point is to find the balance point of goals and values between economic development and carbon emission reduction.(5)Research on standard specifications of carbon emission reduction.It is necessary to strengthen the study on statistical computing methods of carbon footprint,estimation criterion of carbon emission intensity, controlling targets of carbon emission reduction in accordance with national ecological situation in China,etc.
