減排與增長:服務業(yè)如何實現(xiàn)綠色均衡發(fā)展?

摘要： 服務業(yè)是中國經(jīng)濟轉型和產(chǎn)業(yè)結構升級的重要抓手,在資源與環(huán)境"雙重"約束日益趨緊的背景下,有必要研究服務業(yè)綠色發(fā)展問題。能否在減排成本最小的前提下提高服務業(yè)增長率,走出一條綠色發(fā)展路徑?為此,文章創(chuàng)新性地將排放權交易市場引入服務業(yè)部門,采用方向性距離函數(shù)、非線性規(guī)劃等實證研究方法測算2004-2012年中國服務業(yè)14個細分行業(yè)的綠色效率和碳排放影子價格。研究表明:中國服務業(yè)發(fā)展方式并非"綠色",服務業(yè)減排成本和碳排放量逐年增長,減排面臨巨大的經(jīng)濟壓力;在文章設計的排放權交易模型下,服務業(yè)細分行業(yè)能夠形成一個統(tǒng)一的影子價格,從而實現(xiàn)一條綠色發(fā)展路徑,該路徑滿足帕累托有效和投入產(chǎn)出技術有效;在均衡路徑上,流通服務業(yè)應出售排放權,而其他減排成本較高的服務業(yè)購買排放權。
Reducing emissions and safeguarding the sustainability of economic and social development have become critical concerns around the w ord,especially in China-the largest carbon emitter. On the other hand,service industry is the key of China's economic transformation and industrial structure upgradation. How to achieve a w in-w in situation betw een emission reduction and economic grow th in service industry has become an important research topic. Therefore,this study aims to investigate the green development issue of service industry in China,so as to find an equilibrium grow th path w hich minimizes the loss caused by emission reduction. Based on the related literature,this study introduces an emission trading mechanism into service industry,and develops a model of carbon emission right trading. Specifically,this study adopts the directional distance function,nonlinear programming,input-output analysis,as w ell as stochastic frontier analysis methods. With these methods,this study estimates the green efficiency and shadow price of carbon emission for 14 service industries of China from 2004 to 2012. In addition,this study empirically and counterfactually analyses the static and dynamic equilibriums.Under the framew ork of a macro total factor production function,this paper selects relevant theories on environmental production technology as a starting point to explore the allocation of carbon emission.An output-oriented model is initially used to describe the total factor production process. Through theoretical and empirical exploration,the follow ing results are obtained.( i) The abatement cost and emissions of CO2 increased year by year,so Chinese service industries face enormous emission-reduction pressure and the development of Chinese service industries is not green.( ii) The service industries can achieve a uniform CO2 shadow price under the carbon emission right trading model designed in this study,implying that the service industries can achieve a green equilibrium path,w hich is Pareto efficient and technical efficient.( iii) On the equilibrium path,the circulation service industry should sell emission permits,w hile the other service industries could buy emission permits.( iv)Compared to the past studies,the allocation mode of carbon emission in this study is more efficient and reasonable,but the Chinese government should regulate and subsidy the carbon emission right trading market.The above conclusions can offer some useful policy implications for future emissions reduction in China. To reduce carbon emissions more efficiently,China should focus on both the manufacturing and service industries, and pay more attention to the circulation service industry. The Chinese government should also strive to build inter-regional and inter-industrial cooperative emission-reduction platforms,and encourage enterprises w ith greater efficiency to offer technological support to those w ho are lacking to narrow the gap in emission efficiency. Finally,this study offers a theoretical mechanism for carbon emission trading. The government should take measures to implement the mechanism,for examples,supervise the emission trading market,subsidy the enterprises w ith high efficiency,and impose Pigovian tax upon polluting enterprises.
