创新驱动、产权保护与数字技术创新“量质齐升”——基于多重政策组合新视角

Innovation-driven,property rights protection and“quantitative and qualitative rise”of digital technological innovation:a new perspective based on multiple policy combinations

数字技术创新已成为塑造国家、区域间竞争格局的重要因素,而如何发挥多重创新政策组合对数字技术创新的促进效能,是经济新旧动能转化时期亟须回答的重要现实问题。基于2006—2021年中国283个地级市的面板数据,构建多期双重差分模型(DID)系统考察了创新型城市、知识产权示范城市“双试点”对区域数字技术创新“质量”和“数量”的影响。研究表明:(1)“双试点”有利于协同促进区域数字技术创新“质量”和“数量”同步提升,该结论在一系列稳健性检验后仍成立,且其能发挥比“单试点”更为明显的“量质齐升”效应,还能进一步实现以“数量”促“质量”的动态创新激励效果;(2)“双试点”不仅能直接促进区域数字技术创新“质量”和“数量”,还可通过资源配置效应、人才集聚效应以及创新创业效应间接促进数字技术创新“量质齐升”;(3)“双试点”的政策效应具有显著的异质性,这种积极作用在先进行知识产权示范城市建设再成为创新型城市的地区,以及官僚组织冗余较低、对外开放程度较高的地区中更为明显。研究结论对试点城市统筹多重创新政策组合、加快实现数字创新驱动发展具有重要启示。

Digital technological innovation has become an important factor in shaping the competition pattern between countries and regions,and how to play the effectiveness of multiple innovation policy combinations in promoting digital technological innovation is an important practical question that needs to be answered in the period of transformation of old and new driving forces of the economy.Based on the panel data of 283 prefecture-level cities in China from 2006 to 2021,this paper constructs a multi-period difference-in-differences model(DID)to systematically investigate the effectiveness of the“double-pilot”of innovative cities and intellectual property demonstration cities on the“quality”and“quantity”of regional digital technology innovation.The findings suggest the following.(1)“double pilot”is conducive to the synergistic promotion of“quality”and“quantity”of regional digital technology innovation,and it can play a more important role than“single pilot”.Moreover,the“double-pilot”can also realize the dynamic innovation incentive effect of promoting“quality”with“quantity”.The above conclusions are still valid after a series of robustness tests.(2)“double pilot”can not only directly promote regional digital technology innovation in terms of“quality”and“quantity”,but also indirectly promote digital technology innovation in terms of“quality”and“quantity”through the effect of resource allocation,talent concentration and innovation and entrepreneurship.(3)The policy effect of“double pilot”has significant heterogeneity,and this positive effect is more obvious in the region where intellectual property demonstration cities are constructed before becoming innovative cities,as well as in the region with lower redundancy of bureaucratic organisations and higher degree of openness to the outside world.The findings of this paper have important insight for pilot cities to coordinate multiple innovation policy combinations to accelerate the realisation of digital innovation-driven development.
