Abstract
以淮海经济区的20个城市作为研究样本,运用OLS和工具变量 (IV) 回归的方法探求收入不平等及知识产权保护对于城市创新的影响。另外,详细论述了模型中存在的内生性问题,并引入了地理意义上的外生变量。结论表明:① 强的知识产权保护有利于带动淮海经济区的城市创新,这个结论也验证了大量的国内外研究;② 强大的中产阶级的存在有利于促进城市创新。由于本文是为数不多的对该领域的探索,并且样本量过小,所以第二个结论能否被推广还有待被更大范围的数据验证,但该结论对淮海经济区却有很强的针对性。基于此,提出了如下建议:加强知识产权保护及配套制度的制定、缩小城乡和城市之间的差距,以及加强区域中心城市功能。
Taking 20 cities in Huaihai Economic Zone as an example, the study employs OLS and Instrument Variable to explore the influence of inequality and intellectual property rights protection on urban innovation. Meanwhile, the study notes endogenous problem of models and introduces geographically exogenous variables. The findings include: ①stronger intellectual property rights protection promotes innovation abilities of Huaihai Economic Zone, which also validates a large number of domestic and foreign studies; ②larger middle class share is an importantly positive determinant to innovation. These conclusions have strong pertinence to Huaihai Economic Zone, while because this study is a new try and sample size is small, the generalization of the second conclusion is still to be verified by a wider range of data. Therefore, we put forward the following advices: strengthening institution of intellectual property rights protection and its supporting system, narrowing the gap between urban and rural areas, as well as cities, and improving the functions of regional central city.
