Co-evolution of spin-off and networks in regional concentrations: the example of the Research Triangle Park in North Carolina/USA

许多研究发现，作为区域集群出现和增长的主要决定因素的形成类型是附带利益。但是，关于广泛的区域附带进程背后的原因，存在着有争议的辩论。在经济地理学中，区域网络等外部性被视为决定性因素，而这些外部性大多在定性案例研究中进行分析。基于Klepper（2007）的研究认为，原因在于公司特有的因素：增长率高于平均水平、常规良好的公司将其常规继承给其衍生产品，这些衍生产品的增长率再次高于平均水平，随后可能导致大规模的区域集中。这些研究采用了计量经济学方法。在分析研究设计中附带利益和区域网络的形成时，拟议的研究项目应有助于这一辩论。该研究项目从附带利益和区域网络的共同演变这一论题开始：区域范围内的相互作用是附带利益进程的基础，区域网络是本地化附带利益进程的结果。这些过程将在北卡罗来纳州的研究三角园区的信息和通信技术和生命科学产业中进行探索。将定量网络与生存分析有机地结合起来。定性访谈使我们能够详细分析分拆背后的过程。（2007）：分歧，分拆，以及底特律作为美国汽车工业之都的演变。In：Management Science 53（4），616-631.

The type of formation that many studies detect as a major determinant for the emergence and growth of regional clusters is the spin-off. But there is a controversial debate regarding the cause behind extensive regional spin-off processes. In economic geography, externalities like regional networks, which were mostly analyzed in qualitative case studies, were regarded as determining factor. Studies that base upon the work of Klepper (2007) regard the cause in company-specific factors: companies with above-average growth and good routines inherit their routines to their spin-offs, which again grow above-average and subsequently can result in large regional concentrations. These studies apply econometric methodologies. In analyzing the formation of spin-offs and regional networks within a research design, the proposed research project shall make a contribution to this debate. The research project starts with the thesis of the co-evolution of spin-offs and regional networks: interactions in a regional context form the basis for spin-off processes and regional networks arise as a result of localized spin-off processes. These processes shall be explored in the ICT and life science industries in the Research Triangle Park, North Carolina. Methodically, quantitative network and survival analysis are connected. Qualitative interviews enable detailed analyses of the processes behind the spin-offs.Klepper, S.
