越来越多的区域经济规划上升为国家级发展战略,但有关这些战略实施的创新效应的认识仍然较为模糊且不完善。以黄河三角洲高效生态经济区(“黄三角”战略)为例,采用2005—2013年的县级数据和Tobit回归模型对相关问题进行实证研究。结果表明,国家级区域发展战略的实施对地区创新存在一定程度的正向影响,但这一影响作用事实上并不显著。
More and more regional economic plans have been upgraded to national development strategies, but the understanding of the innovative effects of these strategies is still rather vague and incomplete. Taking the Yellow River Delta efficient eco-economic zone (“Yellow River Delta” strategy) as an example, this paper uses the county-level data from 2005 to 2013 and Tobit regression model to conduct empirical research on the related issues. The results show that the implementation of the national-level regional development strategy has a positive impact on regional innovation to a certain extent, but this influence is not in fact significant.
