摘要
文章在概率迁移模型的基础上分析了无融资约束和存在融资约束两种情况下,转型升级对创新集聚的影响。同时,通过以中国30个省级行政区2000—2012年的面板数据为样本,运用动态的空间误差面板模型实证检验了经济转型升级对创新集聚的影响,得出的结论是:(1)在全国总体、东部地区、中部地区的样本中,经济转型升级对创新集聚产生了显著的正向空间影响,但是在西部地区样本中,经济转型升级对创新集聚的空间影响不显著;(2)从弹性值来看,全国总体、东部地区、中部地区、西部地区样本的NB逼近估计结果都显示企业规模的弹性值最大;(3)滞后一阶的被解释变量的估计系数在全国总体、东部地区、中部地区、西部地区样本中都为正,并且都通过了显著性检验。在实证检验结果的基础上,得出了一些简要的启示。
On the basis of the probability of migration model,the paper analyzes impact of transformation and upgrading on innovation cluster under the financing constraints and no financing constraints. Meanwhile,using the panel data of 30 provincial-level administrative region in China from 2000 to 2012 and dynamic spatial error panel model,the paper empirically tests the impact of transformation and upgrading on innovation cluster. Conclusions are as follows: 1. In the sample of the country overall,the eastern region,and the central region,the economic transformation and upgrading produces a significant positive spatial impact on innovation cluster,but the impact is not significant in western region sample; 2. The NB approaching estimation results of the country overall,the eastern region,the central region,and the western region sample show that the elasticity of firm size is the largest; 3. The estimated coefficient of first-order lag explained variable is positive and significant. On the basis of conclusions of empirical test,some inspiration is proposed.
