Total Factor Efficiency Measure Of Transportation Under The Environmental Regulation

China has ranked second with huge greenhouse gas emissions,and emissions of carbon dioxide of transportation is one of the main sources. In2010,carbon dioxide emissions of transportation occupied18.9%of the whole carbon dioxide emissions in oil consumption industry.It means that the regulation of co2emissions of transpo-rtation has a realistic significance.Most literatures in the past focused on carbon dioxide emissions of industry,but few literatures payed attention to transportation emissions.And quantitative analysis of transportation production technical efficiency under environmental regulation performance is also lacked So such situation has become the starting point of this paper.In this paper, the non-radial directional distance function model based on output has been established, which is the innovation of this paper. The model defined different weights of input and output,because traditional directional distance function would overestimate the efficiency of the production technology due to the equal weightsof input and output. And quantified the intensity of environmental regulation by changing the direction vector of the expected output in this model. In this research, intensity of environmental regulation has been classified as the general strength of regulation and strict strength of regulation. We calculated the efficiency of production technology of transportation of28provinces and cities in the two cases during2000-2010, getting the changes of efficiency and ranking of28provinces and cities under different intensity of regulation. The result is that Fujian, Shandong, Hebei, Henan and Qinghai changes little under two kinds of regulation,so strict environmental regulation shall be appropriate. Henan’s ranking rose obviously under strict regulation,and ranking and efficiency of Qinghai was also better under strict regulation. SoHenan and Qinghai were suitable for strict regulation. Ranking of Shanghai and Hainan dropped sharply under strict regulation,so Shanghai and Hainan were suitable for general environmental regulation.Other provinces and cities changed little, so making policy should adjust measures to local conditions. Then we corrected the index of productivity of Malmquist-Luenberger based on new model,And breaked it down for efficient change and technological progress to analyze the relationship between environmental regulation and economic growth. The results showed that technological progress of provinces and cities in the east was more than1under two kinds of regulation strength, verifying the Porter hypothesis. And the technological progress was higher under strict regulation.Central regions were technology retrogression under the general environmental regulation, which can’t verify the Porter hypothesis. But the rate of technological progress under the strict regulation was more than1,verifying the Porter hypothesis.Provinces and cities in the west were the lowest,and technological progress was more than1only under the condition of strict regulation.
