SNA-2008把原称为“无形固定资产”的资产改称为“知识产权产品”。因此,知识产权产品是一个全新的概念,这修改凸显了知识产权产品在评价经济发展中的重要性。由此,本文基于2005-2013年中国30省市知识产权产品发展水平有关的数据,运用突变级数法建立知识产权产品和发展水平评价指标体系,得出综合评价结果,然后运用空间面板模型对30省市的知识产权产品水平进行收敛性分析。分析结果表明,中国区域知识产权产品发展水平呈现收敛状态。

SNA-2008 changed “intangible fixed assets” into “intellectual property products” and expanded its definition. Thus, intellectual property product is a new concept, which shows the importance of intellectual property products in evaluating economic development. Therefore, this paper collects some data about intellectual property products level of 30 provinces in China from 2005 to 2013, using catastrophe progression method to establish intellectual property products index systems and get the evaluation results. Then, spatial panel model is employed to analyze the convergence among 30 provinces in China. And the test suggests that the regional intellectual property products development level is in convergence situation.
