摘要: 创新是经济发展的第一动力,作为创新活动载体的工业用地,其在空间上的配置扭曲对城市创新造成何种影响,是关乎区域经济高质量发展的重大问题。基于2008~2019年长三角地区41个城市面板数据,运用空间计量模型、中介效应模型,考察工业用地空间错配对城市创新的影响差异及作用机制。研究结果表明:(1)从工业用地空间错配类型来看,长三角地区中心城市大多呈短缺型错配,外围城市大多呈过剩型错配。(2)样本考察期内,长三角地区创新水平总体有所提升,且外围城市比中心城市提升幅度更大;空间上,城市创新水平由东向西梯次递减,逐渐形成以上海、南京、杭州为中心的创新连绵区。(3)工业用地空间错配对城市创新具有显著的负面影响,并且这一负面影响在短缺型错配的地区、土地依赖度较高的行业和土地约束较强的时段内更明显;在过剩型错配地区,工业用地空间错配对城市创新存在负向空间溢出效应。(4)对于过剩型错配地区,工业用地空间错配通过创新资金挤出机制和创新环境破坏机制阻碍创新水平提升;对于短缺型错配地区,工业用地空间错配主要通过创新资金挤出机制阻碍创新水平提升。进一步得出的启示是,扎实推进工业用地空间错配的纠偏,是破除城市创新障碍、助力长三角地区高质量发展的有效措施。

Abstract: Innovation is the primary driving force of economic development. As the carrier of innovation activities, the spatial configuration distortion of industrial land and the impacts were the major issues related to the high-quality development of the regional economy. Based on the panel data of 41 cities in the Yangtze River Delta region from 2008 to 2019, this paper used the spatial econometric model and the intermediary effect model to investigate the impacts and mechanism of industrial land spatial mismatch on urban innovation. The results showed that: (1) From the perspective of industrial land misallocation types, most of the central cities in the Yangtze River Delta region were identified as deficient misallocation, while most of the peripheral cities were identified as excess misallocation. (2) During the study period, the innovation level in the Yangtze River Delta region was generally improved, and the improvement rate of peripheral cities was greater than that of central cities; In terms of space, the level of urban innovation decreased from east to west, and gradually formed a continuous innovation zone centered on Shanghai, Nanjing and Hangzhou. (3) The spatial mismatching of industrial land had a significant negative impact on urban innovation, and this negative impact was more obvious in areas with deficient mismatching, industries with high land dependence and for periods with strong land constraints; In excess mismatched areas, there existed a negative spillover effect of industrial land spatial mismatching. (4) For the excess mismatching area, the spatial mismatching of industrial land obstructed the improvement of the innovation level through the innovation capital extrusion mechanism and the innovation environment destruction mechanism; For the deficient mismatched areas, the spatial misallocation of industrial land mainly hindered the improvement of innovation level through the mechanism of innovation capital extrusion. This study implied that promoting the correction of industrial land spatial mismatch was an effective measure to break the barriers to urban innovation and help the high-quality development of the Yangtze River Delta region.
