Given the size of China and its global importance, the book then review s China?s current energy situation and fills the gaps in the literature for those who are interested in and concerned about China?s economic development and energy reform in the new millennium. The book is different from previous studies in several important ways. Firstly, it presents recent, pioneering research rather than a simple textbook, several sections of which have been published in high-quality energy journals. Secondly, subdivides China's energy intensity change into aspects of budget constraint, technological change, factor substitution, energy demand and economic growth using a newly developed econometric approach. Thirdly, it provides many new and different econometric findings and derives many new policy implications for China's energy economy. And lastly, it brings to light a wealth of new knowledge for those who are interested in China's energy economy, the world energy market and global environmental and climate change issues.
