创新空间网络绩效评价方法初探

Preliminary Study on the Performance Evaluation Methods of Innovation Spatial Networks

随着知识经济的崛起,创新成为城市的重要职能之一,并且产生了新的空间需求。从创新空间网络的视角出发,对创新网络与空间结构的相关性进行研究,有助于营造适应创新活动需求的城市空间环境,促进创新活动与空间营造良性互动。创新空间网络的绩效评价包括邻近性、集聚性、中介性、持续性等四个维度以及个体和群体两个层面。运用UCINET和UNA建立创新网络模型和空间网络模型,进而基于ArcGIS实现两类模型的数据转换,可对创新空间网络绩效进行量化可视评价。

Innovation has become one of the most important functions of contemporary cities along with the rising of knowledge economy and it has posed new spatial requirements on the cities.From the perspective of innovation spatial networks,optimizing the interrelations between innovation networks and spatial structures helps to adapt the urban spatial environment to innovation activities and to promote the mutual beneficial interaction between innovation activities and spatial creation.Evaluation on the performance of innovation spatial networks can be carried out from four dimensions such as proximity,agglomeration,intermediary and accumulation and in terms of both individual and group network indicators.Innovation network models can be established via UCINET while spatial network models can be via UNA.Their data can be converted via ArcGIS for comparative evaluation of innovation spatial networks in a quantified and visualized way.
