Abstract:

The main influencing factors of carbon emission performance include economic structure, energy consumption structure, regional division of work and technical level of high-carbon industry. Although these indicators are in a certain degree of influence on CO2 emissions per unit of GDP, it is difficult to measure the contribution of each indicator. In this paper, we selected the four main indicators mentioned, according to the entropy method to measure the weight of each indicator, applying multi-indicators cluster analysis methods under the index system, and dividing the whole country into 7 typical areas. The analysis result shows: the characteristic of the regional division of work, which has the largest weight of 0.4567, is the main factor resulting in regional differences in China’s provincial carbon emissions performance, then the energy structure and the technical characteristics of high carbon industry take the second place. The indicator of economic structure, with a weight of 0.0971, has a limited contribution to explain the regional differences at the provincial level of carbon emissions. In northern regions, the high share of high-carbon production market and low technical level results in low carbon emission performance. Especially in North China, the high proportion of coal in the energy consumption has a negative effect on carbon emission performance; in southeast coastal areas, due to its advanced technology, the negative effect from high share of high-carbon production has been offset to some degree; although the share of high-carbon production in central and western China is much lower than in the eastern regions at present, yet the technical level is low. The carbon emission performance decreased with a backward technical level. There are differences among the historical development of provinces; natural resource endowment and regional division of work, complying with the macroeconomic development of objective laws and economic location theory, in addition to a small number of developed areas, the other regions in China are difficult to change their economic and energy structure in a short period of time. The low-carbon policies should be focused on improving the technical level of high-carbon industries.
