借助于社会网络分析方法对广东省陈村花卉产业集群技术扩散网络进行分析,对其网络密度、平均距离、网络中心度等指标进行测算。研究发现：陈村花卉产业集群内企业之间的技术获取渠道比较单一,多依赖于陈村花卉世界有限公司等核心企业,而此类企业的技术获取门槛较高,增加了中小企业的获取成本,不利于技术的溢出和扩散,行业协会在技术交流与扩散中的作用不明显；同一地缘关系是集群技术扩散网络形成的社会基础,市场合作产生的技术溢出是集群技术扩散网络形成的直接原因。网络呈现出“核心—边缘”结构,其中陈村花卉世界有限公司处于最核心位置；其次是台资和外资企业,它们占据了核心层的多数,对陈村花卉产业集群的发展起较强的控制作用,而本地中小企业和传统种植户处于边缘位置。集群技术源较单一,产学研发育不明显,对台资和外资的技术溢出依赖性强。

With the help of social network analysis method to the Chen-cun flower industrial cluster of Guangdong province. We do the study of social network analysis to the network density, average distance, network centralization and the core-edge structure. Chen-cun flower industrial cluster of enterprises access to technology is relatively single, much depends on the Chen-cun flower world LTD, but higher threshold of technology acquisition of such enterprises, increased the cost of small and medium-sized enterprises to obtain, is not conducive to technology spillover and diffusion, the role of industry association in technical communication and diffusion is not obvious, and the same geographical relationship is the social basis for the formation of cluster technology diffusion network, and the technical spillover of market cooperation is the direct cause of the formation of cluster technology diffusion network. The network presents the structure of “core – edge”, among which Chen-cun flowers world LTD is in the most central position; followed by more Taiwan enterprises and foreign enterprises, they occupied most of the core layer, the development of Chen-cun flower industrial cluster on the stronger control function, traditional and local small and medium-sized enterprises and farmers in a edge position. It is not obvious that the technology of cluster technology is single, the development of industry and research is not obvious, and the local enterprises have strong dependence on the technology spillover from Taiwan enterprises and foreign enterprises.
