【摘要】 建筑市场是一个由复杂社会网络关系构成的系统,企业的竞争力和其在网络结构中的位置和把握网络机会的能力相关。论文从项目合作视角出发,通过建立建筑业企业社会网络模型,并利用区域性案例进行实证。结果发现建筑业不同类型的企业在网络中的位置具有显著不同,服从幂律分布,但本地国有企业占有明显优势,存在市场开放度和竞争不足问题;进一步的,论文通过实证得出了企业市场竞争力受中心度和结构洞中的限制度指标的双重影响,且两个因素之间存在幂律关系。论文的实证结论证明,在不完全竞争条件下,企业要提高自身在建筑市场的竞争力,必须尽可能利用地缘社会关系和政府资源关系,创造和利用网络结构洞,巩固自身在网络中的位置,尽力提高网络个体中心度。更多还原

【Abstract】 Construction market is a complex system that consists of social network relations,and there is significant correlation between enterprises’ competitiveness and their location in the network and ability to seize opportunity.Based on projects network,social network for construction industry is established for empirical analysis using regional case.The outcome shows that different types of enterprises in the network have a significantly different position,which follows a power law distribution,and local stated-owned enterprises have the remarkable advantage,therefore there is a lack of market openness and competition issues.Furthermore,through empirical analysis,construction market competitiveness is affected by both centrality and constraint index in structural hole,and the two independent variables follows power law relationship.The findings manifest that,under conditions of imperfect competition,enterprises must improve their competitiveness in construction market to improve individual centrality,by the means of not only utilizing geo social relationship and government resources relationship as much as possible,but also creating and using structural hole to consolidate its position in network.更多还原
