Study on the Phenomenon of Unbalanced Distribution of Value-added of Construction in China

There is a very serious phenomenon of unbalanced distribution of value-added of construction among different regions in China. This paper first uses Theil index to analyze the inter-and intra-regional differences of value-added of construction. An indicator system then is established of the possible influencing factors of the value-added of construction. After that the approach of grey relation is applied to identifying the sensitive factors that influence the value-added of construction in each province. The similarities and differences of those factors are further probed so as to find out the specific causes which lead to the intra-regional differences among the provinces in the eastern region as well as the inter-regional differences among the three regions of China. Benefited by the logical conclusion of the paper, we can see more clearly the problems existing in Chinese construction industry and promote its sustainable development.
