Research On Static Structure Analysis And Dynamic Evaluation Of Building Industrialization Ecosystem

With the increasing shortage of natural resource and the gradual loss of demographic dividend in China, it shows imperative to reform those resource and labor intensive industries, especially construction industry, which will help to reduce energy and resource consumption. So far, only a few leading enterprises in China, including Vanke Co., Ltd. and Broad Homes Industrial International Co., Ltd., have attempted to widely deploy industrialized construction technologies. The diffusion of building industrialization in China is now facing server resistance, and some researchers believe that main factors that hinder the development of building industrialization includes diffidence in the industrial system and confusion regarding the structure. Building industrialization is not extensively used in mainland China as compared with developed countries. The development of enterprises is faced with numerous dilemma. The primary cause of this phenomenon is that enterprises never tried to understand the structure characteristics and dynamic evaluation of building industrialization system from a macro-view, and they failed to investigated the structural position, strengths and weaknesses of themselves. Thus, it leads to errors in strategy and chaos of management mode. Therefore, it should be the first priority to properly plan and build the industrial system of building industrialization, to set a exact location for each stakeholder and to optimize the allocation of resource.To begin with, this study defined building industrialization ecosystem (BIE) from a brand new point based on the natural ecology and the industrial ecology, while the elements, like the population and community, were all redefined. According to the background of construction industry in China, the a building industrialization ecosystem (BIE) was built and the operation mechanism of it on ideal condition was stated.Secondly, social network analysis (SNA) was adopted to analyze complex social relationships under the static state of this system. Data was collected via onsite questionnaire surveys and then using the software-UCINET to quantify the characteristics of the entire network and the ego network, structural position of each population and the relationships among them. The results are presented using Netdraw. The core population and the sub-core population of this system were finally identified from the angle of information and resource controlling.Then, based on the classification of ecosystem’s stages, Logistic model was utilized to quantify the evaluation process of the BIE from a micro-level, while the co-evolution trends of core population in the BIE were simulated by Lotka-Volterra model.Finally, political suggestions, which were derived from the results of policy analysis, system static state analysis and dynamic evolution, were recommended to promote the development of BIE in China.Issues studied in this thesis belong to typical cross-disciplines. From the theoretical level, it rebuilt a industrial structure. From the practical level, conclusions in this study will help stakeholders in BIE to deeply understand the structure of the whole system, which will significantly promote the synergetic development and boost the profits of industrialized projects. From the management level, it revealed the forming mechanism and evaluation mechanism of BIE, thus it has vital practical significance to the upgrading of construction industry and the political design for building industrialization in China.
