基于空间计量分析的浙江省区域创新产出研究

以浙江省69个县级行政区作为基本研究单元，以发明专利授权数和新产品产值作为衡量创新产出的评价指标，运用空间自相关、NICH指数、地理加权回归等方法分析浙江省2007年—2019年创新产出的空间分异特征及其影响因素.结果表明：2007年—2019年，浙江省创新产出空间集聚特征显著，高创新产出区的分布与浙江省大湾区“一环、一带、一通道”的总体格局基本吻合；浙江省各县域创新产出存在高值集聚和低值集聚现象，杭州市区及其周围县区、宁波市区及其周围县区以及绍兴市区为热点区域，冷点区域集中分布在浙西南与浙西的山地丘陵地带；由地理加权回归分析发现，技术溢出和空间区位对浙江省区域创新产出具有显著正向影响，产业升级、政府政策和创新投入对创新产出的影响呈现正负差异性，而经济基础对创新产出的影响总体呈负向关系，仅在极少数县域为正相关.

Regional innovation output in Zhejiang Province based on spatial econometric analysis

In this paper， 69 county-level administrative regions of Zhejiang Province are taken as the basic research unit.The number of invention patents granted and the output value of new products are used as the evaluation index to measure the innovation output.Spatial autocorrelation， NICH index， geographically weighted regression and other methods are applied to analyze the spatial differentiation characteristics and influencing factors of innovation output in Zhejiang Province from 2007 to 2019. The results show that the spatial agglomeration of innovation output in Zhejiang Province is significant from 2007 to 2019， and the distribution of high-innovation output areas is basically consistent with the overall pattern of “One Ring， One Belt and One Channel” in the Greater Bay Area of Zhejiang Province. In Zhejiang Province， there are high value agglomeration and low value agglomeration of innovation output at the county level. Hangzhou urban area and its surrounding counties， Ningbo urban area and itssurrounding counties， and Shaoxing urban area are hot spots. The cold spots are concentrated in the mountainous and hilly areas of southwest and west Zhejiang. By geographically weighted regression analysis it's found that technology spillover and the spatial location has significant positive effectson regional innovation output in Zhejiang Province， while the impacts of industrial upgrading， government policy and innovation investment on innovation output have positive and negative difference.And the influence of the economic foundation on innovation output is negative in general， and only in rare county is positive.
