Employment impacts of petroleum industry in China: an input-output analysis

Chinas employment issue is catching peoples eyes at present and for a long time. Economic impacts of Chinas petroleum industry on employment are divided into direct, indirect and induced impacts and they are analysed in this study by using the input-output approach. The research results suggest that petroleum industry will supply 0.0957 jobs and 0.1501 jobs given 10,000 CNY final demand added in extraction of petroleum and processing of petroleum respectively; 1,887 CNY and 2,756 CNY of employment income will be affected given 10,000 CNY final demand added in extraction of petroleum and processing of petroleum respectively; extraction of petroleum has more direct impact on both employment number and employment income given one unit output added, and processing of petroleum has more indirect and induced impact on them. The petroleum industrys impact coefficients on both employment number and employment income have been decreasing since 1987. The proportion of direct impacts in total impacts continues to decrease, and the connection between petroleum industry and other sectors in Chinas national economy has become closer than before.

Nexus Between Energy Consumption and Economic Growth in China: From the Perspective of Embodied Energy Imports and Exports

ABSTRACT The nexus between energy consumption and economic growth in China is analyzed from the perspective of embodied energy imports and exports in this article. The research results suggest that China is a net embodied energy exporter and it is the inevitable result of China’s present economic development model. Exporting embodied energy contributes significantly to China’s economic development, and the trade-off costs of employment, trade surplus and government tax for China to reduce embodied energy exports are very high. China is bound by its own policies and unable to radically change its embodied energy exporting position within the foreseeable future.

The energy efficiency DEA method in value of economic continuity

Energy is of vital importance to economic development in every country nowadays. With the worldwide decreasing trend of energy reserves growth rate, energy efficiency is receiving more and more attentions. This paper focuses on improving the total factor energy efficiency DEA method from the respective of reverse thinking in order to analyse the results in value of economic continuity, and to calculate the TFEE of countries in time series. This paper takes the top ten energy consuming countries in 2011 as examples, and compares the results between the traditional and the improved methods respectively. The results show that energy efficiency calculated from traditional method could be overestimated, and the changing trends of energy efficiency in different periods could not be reflected by the traditional method.
