【摘要】 基于互联网经济转型和信息技术浪潮下的创新创业活动已成为社会广泛关注的热点。论文利用上海互联网新创企业数的截面数据,采用核密度估计、Ripley’s K函数、负二项回归模型等方法探究互联网新创企业的时空演化特征与区位影响因素。结果表明:①时序变化上,互联网创业在2010年后进入活跃期,行业分布与全国创业形势及上海产业导向相一致。②空间演变上,整体呈现"大集聚小分散"的分异特征,企业高度集聚于中环线内的同时向郊区中心镇和新城扩散。中心城区企业集聚强度不断增强,集聚规模由4.5 km扩张到6.5 km;在空间上由相对均衡向多中心集聚的形态演变。黄浦-静安-徐汇片、五角场、陆家嘴、张江和漕河泾等5大核心集聚区以其特定的资源优势获得互联网新创企业的青睐。③孵化环境、生活环境、商务环境、投资环境等构成互联网创业活动的外部环境需求;产业集聚、技术因子和土地价格等对互联网新创企业区位分布产生了显著影响。更多还原

【Abstract】 Innovation and entrepreneurial activities based on the transformation of Internet economy and information technology have become a focus of attention in today’s society. Using the cross-sectional data on the number of Internet start-ups in Shanghai Municipality, this study explored their spatial distribution characteristics and location factors by adopting the methods of nuclear density analysis, Ripley’s K function, and negative binomial regression model. The results show that: 1) Internet entrepreneurship has entered an active period since 2010, and the change is consistent with the situation nationwide and the urban industrial orientation in Shanghai. 2) With regard to the spatial distribution, an overall pattern of agglomeration at the macro level and dispersion at the micro level is present. While highly concentrated within the middle ring, enterprises also spread to suburban central towns and new towns. In the central urban areas, agglomeration intensity has continuously increased, and the scale has expanded from 4.5 km to 6.5 km. The spatial distribution changed from relatively balanced to multi-center agglomerations. The five core agglomeration areas, including Huangpu-Jing’an-Xuhui,Wujiaochang, Lujiazui, Zhangjiang, and Caohejing, have won the favor of Internet start-ups depending on their specific resource advantages. 3) Concerning the influencing factors, incubation environment, living environment,business environment, and investment environment constitute the external environment demand of Internet entrepreneurial activities. Industrial agglomeration, technological factors, and land prices have had significant impacts on the spatial distribution of Internet start-ups.更多还原
