- Abstract
Due to lacking driving force to promote the technology innovation in China construction industry,it may be a better choice to encourage the willing of construction enterprise to undergo the technology innovation by moderate monopoly.So,firstly it is supposed that the super construction enterprise can participate in the industry competition comprehensively,then,this paper proves the possibility to determine the number of monopoly construction enterprises in terms of moderate monopoly by the output mode of enterprise.Secondly,taking the state-owned building enterprise as the main body,it is further supposed that the construction enterprise could improve the productivity by raising the R&D in terms of moderate monopoly and the R&D should be invested in each period of manufacturing,then,this paper has established the utility mode of construction technology innovation by the Lagrange function in terms of moderate monopoly.At last,the finding shows that the technology innovation utility of China construction enterprise is not significant and this conclusion is supported by the growth trend of China construction industry in 1991-2004 and the investigation of the resistance factor to China construction technology innovation.
