What is the Industrial Structure Changes of China?

Although China has made great achievements in economic scale,the model of high-quality economic developments is still in the exploratory stage.A series problems,such as unreasonable industrial structure and low production effciency,need to be resolved urgently.The transformation and upgrading of industrial structure is the inevitable choice.The analysis of industrial relations is an important method to reveal the internal mechanism of industrial structure change.Therefore,based on the concepts of sensitivity and influence coeffcient,this paper proposed the concepts of driven and driving coeffcient,and constructed the industrial complex networks of China from 1999 to 2013 according to the EORA input-output table.From the perspectives of the interaction power,industrial linkages and community structure,this paper systematically analyzes the evolution of China’s industrial structure.Results show that China’s industrial structure is undergoing a transformation from industry-oriented to industry-service-oriented.The interaction linkages between industries has formed a robust association structure.The traditional sectors such as infrastructure construction and industries are still the largest consumer group driving the development of other industries.Besides,light industry,infrastructure construction and finance have become increasingly important hub industries in the industrial system.However,some unbalanced community structures are formed in the economic system,which has resulted in a waste of resources and low production effciency to a certain extent.Effectively grasping the relationship between China’s industrial structure evolution and its association is conducive to formulating economic restructuring policies,promoting the upgrading of China’s economic and,realizing the leap from quantitative change to qualitative change.

Energy Consumption in China's Construction Industry: Energy Driving and Driven Abilities from a Regional Perspective

The construction industry is one of the largest energy consumers in China. It not only uses energy directly but also consumes a large amount of embodied energy hidden in intermediate goods and services from other industries. This paper utilizes the multi-regional input-output(MRIO)model to measure the embodied energy consumption in China's construction industry at the province level. To quantify the backward and forward linkages between the construction industry and other industries, the energy-driven and energy-driving abilities of the construction industry are investigated for 30 provinces. The results show that the values of the energy-driven coefficients are significantly larger than the energy-driving coefficients, indicating that the construction industry is highly dependent on products from other industries and other regions, not vice versa. The construction industries in the southwest and northwest regions of China have the highest energy-driven coefficients, showing that the construction industries in west China heavily rely on indirect energy embodied in goods and services. This particularly applies in Guangxi and Hainan provinces, which have the highest energydriven abilities and the lowest energy-driving abilities. The findings can facilitate the policy-makers to examine the critical energy-saving paths.
