数字技术应用成为推动经济增长的关键要素,其产业空间集聚成为“新经济地理学”关注的前沿命题。文章基于2016—2021年微观企业数据,通过Scholl集聚指数方法测度数字技术应用业及其细分行业的集聚程度,并采用空间分析方法对浙江省数字技术应用业空间集聚演化特征进行了研究,主要结论为：①整体沿环杭州湾形成“核心区域+外围廊道”空间格局并呈“单核心”向“多核心”演化趋势,“杭—义—金—衢”“台—温”组团型产业发展轴初见雏形。②各城市及分行业新增企业数量未出现专业化趋势但马太效应显著,存在空间重组现象,信息技术服务业作为优势产业与软件开发业呈“橄榄型”分布。③细分行业集聚演化趋势与行业属性相关。信息技术服务业、软件开发业、互联网相关服务业偏集聚并在空间演化上高度耦合;电信、广播和卫星传输服务业偏分散且需依托片区核心实现数字技术转型,其他数字技术应用业作为高精尖产业附属无明显集聚分散特征。最后基于“一湾引领,三轴带动”的多组团型产业空间结构提出“规划对接+专业化+制度保障”的发展建议。
The application of digital technology has become the key factor to promote economic growth,and its industrial spatial agglomeration has become the frontier proposition of "new economic geography". Based on the data of micro enterprises from 2016 to 2021,this paper calculates the agglomeration degree of digital technology application industry and its subsectors by Scholl agglomeration index,and uses spatial analysis method to study the spatial agglomeration evolution characteristics of digital technology application industry in Zhejiang Province. The main conclusions are as follows: 1) It overall shows the "core region-peripheral corridor" spatial pattern along Hangzhou Bay,and the evolution trend is from the "single core" to the "multi-core". The cluster industrial development axis of "Hangzhou-Yiwu-Jinhua-Quzhou" and "Taizhou-Wenzhou" has taken on the shape. 2) The number of new enterprises in each city and sub-industry did not show a trend of specialization,but the Matthew effect was significant and there was a phenomenon of spatial reorganization. As a dominant industry,the information technology service industry and the software development industry show an "olive-shaped" distribution. 3) The agglomeration evolution trend of segmented industries is related to industry attributes. Information technology service industry,software development industry and Internet-related service industry tend to cluster and are highly coupled in spatial evolution. The telecommunication,broadcasting and satellite transmission services are scattered and need to rely on the core of the region to achieve digital technology transformation. Other digital technology application industries,as a high-end industry affiliated,do not have obvious agglomeration and dispersion characteristics. Finally,based on the multi-cluster industrial spatial structure of "one bay leading and three axes driving",it proposes the future development proposal of " planning docking +specialization + institutional protection ".
