【摘要】 伴随着建筑业的转型升级,工业化建筑因其施工效率高、周期短、节能减排、环境保护等特点备受社会各界关注。然而由于我国的建筑工业化起步较晚,产业链主体普遍割裂导致工业化建筑无法形成规模化,产生了成本高、质量低、工期拖延等一系列问题。知识共享作为产业链整合的途径之一,可以提高主体之间的协作效率、降低协调成本、加强合作,有助于减少由于不适当的沟通造成的损失。因此,在工业化建筑产业链中发挥知识共享的协同作用,促进企业合作从而提高产业链的整体生产绩效已然成为当前亟需研究的重要课题。本文对工业化建筑产业链主体的知识共享行为展开研究,在整理归纳文献和梳理相关理论概念的基础上,分析了工业化建筑产业链中知识共享的现存问题,针对问题界定了本研究的产业链主体为PC构件制造商、承包商和开发商,又基于三者探讨了知识共享的必要性和可行性,并运用实证分析从成本-收益角度对产业链主体知识共享的主要影响因素进行了识别。依据识别的影响因素建立三方演化博弈模型,通过单方和混合策略稳定性分析探究了工业化建筑产业链上PC构件制造商、承包商和开发商的知识共享策略和演化路径,求得系统趋于理想状态的初始条件。在满足初始条件的设定下,基于系统动力学理论构建SD-演化博弈模型,仿真分析7个影响因素的变动对主体知识共享策略选择的影响,依照仿真结果分别从开发商、PC构件制造商和承包商角度对工业化建筑产业链主体的知识共享提出了对策建议。研究结果表明产业链主体进行知识共享的概率与激励系数和惩罚系数正相关,但过度的激励会带来不良的影响;与共享成本负相关,且双方主体均降低共享成本的结果优于单方主体,存在仅单方主体降低共享成本的系统最优解;与原始成本正相关,当双方主体均为较高原始成本和一方为高原始成本另一方为低原始成本时系统趋于知识共享;与开发商的监管成本和收益系数无关,无法通过优化来改变产业链主体的知识共享意愿。本研究旨在促进产业链主体的知识共享,以期为工业化建筑产业链的优化提供理论指导。更多还原

【Abstract】 With the transformation and upgrading of the construction industry,industrialized construction buildings are widely concerned by the community because of its high construction efficiency,short construction period,energy saving and emission reduction,environmental protection and other characteristics.However,due to the late start of China’s construction industrialization,the main body of the industrial chain is generally split,leading to the scale of industrial construction can not be formed,resulting in a series of problems such as high cost,low quality,delay in construction period and so on.As one of the effective ways of industrial chain integration,knowledge sharing can improve the efficiency of cooperation between the main bodies,reduce the cost of coordination,and strengthen the cooperation among the main bodies,which helps to reduce the loss caused by improper communication.Therefore,it has become an important issue to play the collaborative role of knowledge sharing in the industrial chain of industrialized construction,promote enterprise cooperation and improve the overall production performance of the industrial chain.This paper studies the knowledge sharing behavior of the main body in the industrial chain of industrial construction.On the basis of summarizing the literature and combing the relevant theoretical concepts,the existing problems of knowledge sharing in the industrial chain of industrialized construction are analized,the main body of the industrial chain as PC component manufacturers,developers and contractors are defined,the necessity and feasibility of knowledge sharing based on the three bodies are discussed,and the empirical analysis is used to identify the main influencing factors of knowledge sharing from the perspective of cost-benefit.Based on the identified influencing factors,a tripartite evolutionary game model is established.Through the stability analysis of unilateral and mixed strategies,the knowledge sharing strategies and evolutionary paths of PC component manufacturers,developers and contractors in the industrial construction industry chain are explored,and the initial conditions of the system tending to the ideal state are obtained.Under the initial conditions,SD evolutionary game model is constructed based on the system dynamics theory.The influence of the changes of seven factors on the selection of the main knowledge sharing strategy is analyzed,and puts forward countermeasures and suggestions for the knowledge sharing of the main body of industrial construction industry chain from the perspective of developers,PC component manufacturers and contractors.The results show that the probability of knowledge sharing is positively related to the incentive coefficient and punishment coefficient,but excessive incentive will bring adverse effects;it is negatively related to the sharing cost,and the result of both bodies reducing the sharing cost is better than that of one body,and there is a system optimal solution of only one body reducing the sharing cost;it is positively related to the original cost,when both bodies are independent The results show that the system tends to knowledge sharing when the original cost is high and the initial cost of one side is high and the other side is low;it has nothing to do with the supervision cost and profit coefficient of developers,and it can’t change the knowledge sharing willingness of the main body of the industrial chain by optimizing the coefficient.This study aims to promote the knowledge sharing of the main body of the industrial chain,in order to provide theoretical guidance for the optimization of the industrial chain of industrialized construction.更多还原
