TitleEvaluating the Low-Carbon Efficiency of the City and Analyzing Its Influential Factors
作者Yu-Sheng Shen, Hsiao-Lan Liu

Facing the disasters and threats stemming from global warming and climate change, most city governments in the world have set up low-carbon development as a goal, and drawn up low-carbon policies to achieve this goal. However, the effects of those low-carbon policies are not possible to clarify. The development of the city/county has brought about economic benefits, but it also consumed significant resources and produced carbon emissions and environmental pollutants. Therefore, how to evaluate benefit and loss comprehensively and offer improvable recommendations is a key issue in the sustainable and low-carbon development of the city/county. In the past, most researchers evaluated low-carbon efficiency by indicators, and proceeded to their evaluation without considering the negative externalities arising from development, therefore, making inaccurate assessments of low-carbon efficiency evaluation. Thus, this paper assesses the low-carbon efficiency of the city by the Bad Outputs model of the DEA, and analyzes its influential policies by the Tobit model. According to the results of the Bad Outputs Model, Taipei City, Hsinchu City, Taitung County, and Hualien County are efficient, and have achieved an optimal scale level. Another result of the Tobit model indicates that the industrial unit has a negative impact on the low-carbon efficiency of the city. Moreover, resource recovery, the total length of the urban bus route, green buildings, and green areas all have a positive impact on the low-carbon efficiency of the city.
