| Summary/Abstract |
China plans to reduce carbon dioxide emissions from 2005 levels by 40–45% by 2020 and by 60–65% by 2030. This research project addresses this challenge by analyzing Chinese provincial carbon dioxide emission efficiencies and the energy consumption structure. The study applies the Slacks Based Measure (SBM) model to analyze the data from 30 regions in China from 2000 to 2011. The situation of provincial carbon dioxide emission efficiency, the characteristics of the energy consumption structure in each province, and the differences among these provinces are quantitatively analyzed. Based on the K-means cluster analysis, this research suggests that China be divided into five groups in the energy consumption structure: the inefficient and less reasonable group, the inefficient and more reasonable group, the efficient and less reasonable group, the efficient and more reasonable group, and the efficient and most reasonable group. The study offers recommendations for the government to develop policies to effectively and efficiently reduce carbon dioxide emission levels for each group. It also has profound implications for government administration in developing countries to guide the energy consumption and to control environmental pollution for the healthy development of the economy.

| Summary/Abstract |
Fossil energy subsidies reform would be an effective way to improve the energy consumption structure; however, the reform needs to be assessed comprehensively beforehand as it would exert uncertain impacts on economy, society and environment. In this paper, we use price-gap approach to estimate the fossil energy subsidies of China, then establish CGE model that contains pollutant emissions accounts and CO2 emissions account to stimulate the fossil energy subsidies reform under different scenarios, and the environmental economic analysis concept is introduced to monetize the pollutant reduction benefits. Furthermore, we analyze the possibility and scope of improving the energy consumption structure from the perspective of technical and economic analysis. Analytical results show that the energy consumption structure could be improved by different extent by removing coal or oil subsidies, while the economic and social indexes will be influenced distinctively. Meanwhile, the effects of cutting coal subsidies are more feasible than that of cutting oil subsidies overall. It is recommended to implement fossil energy subsidies gradually, cut the coal first and then cut oil subsidies successively.

| Summary/Abstract |
Innovation-driven, energy consumption structure optimisation is crucial in developing countries. China, as a typical developing country, has been shifting its economic development model from a traditional approach to innovation-driven, high-quality development. We select nine resource-based regions in China as our research subject and employ a varying coefficient panel model and a Hansen panel threshold model to quantify the marginal and threshold effects of innovation capacity in optimising energy consumption structure. The results indicate that the overall energy consumption structure index for the analysed regions is 0.563, revealing that the structure is rather low and regional economic development relies mainly on low-ranked energy. Astonishingly, the marginal effect reflects obvious heterogeneity: a positive effect in Sichuan (−0.208), Yunnan (−0.207), and Xinjiang (−0.431); nearly no effect in Chongqing, Gansu, and Qinghai; and a negative effect in Guangxi (0.104), Shaanxi (0.244), and Ningxia (1.282). In previous studies, such negative effects have been totally ignored. Further, there are double thresholds and a unique driving mechanism, namely, ‘negative driving → strong positive driving → weak positive driving’. Interestingly, below the first threshold, improvement in innovation will lead to energy consumption structure degradation. Current policies, such as introducing extensive talent, are not feasible for all resource-based regions. The concerns of policy making for the three different threshold intervals should be: upgrading industrial structures, optimising the structure of human resources, and preventing ‘brain drain’, respectively.

| Summary/Abstract |
This paper investigates the long-run equilibrium relationships, temporal dynamic relationships and causal relationships between energy consumption structure, economic structure and energy intensity in China. Time series variables over the periods from 1980 to 2006 are employed in empirical tests. Cointegration tests suggest that these three variables tend to move together in the long-run. In addition, Granger causality tests indicate that there is a unidirectional causality running from energy intensity to economic structure but not vice versa. Impulse response analysis provides reasonable evidences that one shock of the three variables will cause the periods of destabilized that followed. However, the impact of the energy consumption structure shock on energy intensity and the impact of the economic structure shock on energy consumption structure seem to be rather marginal. The findings have significant implications from the point of view of energy conservation and economic development. In order to decrease energy intensity, Chinese government must continue to reduce the proportion of coal in energy consumption, increase the utilization efficiency of coal and promote the upgrade of economic structure. Furthermore, a full analysis of factors that may relate to energy intensity (e.g. energy consumption structure, economic structure) should be conducted before making energy policies.
