摘要
在产业集群和社会网络理论基础上,通过构建"企业—行业"隶属网络,研究集群网络特征对创新集群成长的影响。通过珠三角地区信息服务业集群数据的实证分析,研究结果表明:企业软件著作权的增加、整网规模的扩大、R&D投入占比的提高、政策推出对产值增长和就业增加有显著的正向影响;集群内企业数量的增长并不能有效提升网络内部信息的传播扩散效应;整网密度的提高会促进集群网络小世界的形成,却不能带来产值和就业的增长;群体中心性的提高会削弱小世界特征的形成,抑制产值和就业的增长;软件著作权、产值和个网规模的增加均对整网规模的扩大有显著的正向作用。
Based on the theory of industrial clusters and social network, we build up affiliation network of ＇enter-prise-industry＇, proposed the model and hypothesis of ＇innovation enterprises growth-network characteristics-innova-tion cluster growth＇. By using empirical analysis on PRD information services industry cluster, we got conclusions that the growth in the number of corporate patents, the expansion of whole network scale, the increase of R＆D investment and the policies have significant positive impacts on the output and employment. The increase in pat-ents, outputs and ego network scale have significant positive impacts on the expanding of whole network scale The increase in whole network density will promote the formation of the small world, but cannot bring about the growth of output and employment. The improvement of group centrality will weaken the formation of small-world character, and inhibit the growth of output and employment. The growth number of firms cannot effectively im-prove the network internal information spread efficiency.
