Empirical Study on Ecological Niche Evaluation on Regional Construction Industry in China

摘要

The ecological system of the construction industry had been divided into three aspects, i.e. economy, scale andtechnology. Basing on the ecological niche theory, this paper established the evaluation model and studied on the ecologicalniche status about national regional construction industry in China using statistical data from 2007 to 2012. The analysisresults show that Jiangsu, Zhejiang and Liaoning have the highest scores in the economic and the scaled niche. Tianjin,Beijing and Jiangsu’s technology niche are better. Overall, Integrated niche still has a better performance in Jiangsu, Zhejiangand Liaoning. The calculated values are 0.1002, 0.0696 and 0.0592 respectively. In terms of the discreteness and thediversity, the score of the scaled niche is the highest. The economic niche’s score is the second. And the lowest score isbelonged to the technology niche. It is also found that the national construction industry has an unbalanced developmentin each area. The construction industry depends on the advantage of the economic investment and scaled advantage in theeastern coastal and the central regions. The level of the management and the technology is still low in the whole industry.Therefore, it is suggested that the Chinese government should enhance the strength of the construction investment and developmentin the north and west regions, ensuring the good developmental situation in the eastern and central regions. TheR&D and the spreading of the technological advanced achievement should be strengthened. And the management and thetechnology level of the construction industry should be improved.
