Carbon dioxide emission is closely related to economy. A rational measurement of carbon emission efficiency is a key step to low carbon economy. This paper uses random frontier model and core density estimation to analyze the panel data of industrial GDP, capital input, laboring input, energy input and industrial carbon dioxide emission in Jiangsu's cities during 2005 to 2015, and carbon dioxide emission performance based on the entire elements framework. Results show that the carbon dioxide emission performance varies as time and space with up to 48.2% in difference, central Jiangsu sitting at the top, and then southern and northern. Lianyungang city ranks the first in emission reduction. This paper presents suggestions on raising Jiangsu's industrial carbon dioxide emission performance from adjusting energy structure, increasing input on science and technology and boosting regional cooperation.
