摘要
基于空间集聚理论和企业创新理论,将产业集聚分为规模集聚和空间集聚两个维度,构建了产业集聚对高技术产业研发投入强度影响作用的计量模型,进而利用1995—2012年高技术产业面板数据对相关参数进行了估计和检验.相关结果表明:高技术产业的规模集聚和空间集聚与其研发投入强度均呈倒U形关系,应重点控制计算机及办公设备制造业的集聚度;在对研发投入强度的作用上,规模集聚和空间集聚存在相互替代效应,中小企业增强了集聚区创新活力,大企业的空间扩张则丰富了集聚所需资源要素;不同的细分行业,集聚对研发投入强度的作用不同.
The industrial agglomeration was divided into two dimensions of scale and spatial agglomerations. The economitric model of the impacts of industry agglomeration on R＆D intensity was built based on the spatial agglomera- tion theory and the enterprise innovation theory. The relevant parameters were estimated by using the panel data of high- tech industries form 1995 to 2012. The main findings are as such follows. There are inverted U-shaped impact relation- ships of scale agglomeration and spatial agglomeration on R＆D intensity. The agglomeration degrees of computer and of- rice equipment manufacturing industry should be limited. There is a mutual substitution effect on R＆D intensity be- tween scale agglomeration and spatial agglomeration. SMEs enhance the innovative dynamism of the clusters. The space expansions of large enterprises enrich the resources required for agglomeration. The agglomeration effect on R＆D inten- sity is different in different segmental industry.
