企业投融资视角下福建省数字产业发展时空演化

数字经济是构建现代化经济体系的重要引擎。企业投资是拉动数字经济增长的重要因素。数字经济产业的发展决策，亟需洞察相关企业投融资的结构性特征及其时空演化模式。本文以“数字中国”的思想源头和实践起点——福建省为研究案例，基于2000—2021年的数字经济企业投融资数据，采用复杂网络分析和负二项回归模型等方法，以地级市为基本研究单元，探究了福建省数字经济企业投融资的空间特征及影响因素，结果表明：① 福建省数字经济企业的投融资规模呈增长趋势，投资来源由以非数字经济企业为主转变为以数字经济企业为主；② 省外投资占比逐步提升，省外投资由2000年的8.56亿元增长至2021年的288.08亿元，占比由11.59%增长至31.06%，融资金额在福建省内“东高西低”的空间分布格局愈发明显；③福州市始终是企业投资首选的福建省内城市，而随着时间的推移，厦门、泉州等枢纽中心不断浮现，集聚形成以其为核心的福厦泉走廊；④ 投融资影响因素中，政策和信息化发展环境对数字经济企业投融资联系具有显著促进作用，地理距离对数字产业投融资联系的影响日益弱化。最后，研究结合福建省数字产业发展的时空演化特征及其影响要素，提出政策建议，以期为“数字福建”建设和福建省数字经济的持续健康发展提供科学支撑。

Exploring the Digital Industry Development in Fujian Province: A Perspective of Enterprise Investment and Financing

The digital economy is an important engine for building a modern economic system. Corporate investment is an important factor driving the growth of the digital economy. The development and decision-making of the digital economy industry requires an urgent insight into the structural characteristics of the investment and financing of related companies and their temporal and spatial evolution patterns. This paper takes Fujian Province, the ideological source and practical starting point of "Digital China" as a research case, based on the investment and financing data of digital economy enterprises from 2000 to 2021, adopts complex network analysis and negative binomial regression model, and takes prefecture-level cities as the basic research unit to explore spatial characteristics and influencing factors of investment and financing of digital economy enterprises in Fujian Province. This research finds that: firstly, the investment and financing scale of digital economy enterprises in Fujian shows an increasing trend, and the source of investment has changed from non-digital economy enterprises to digital economy enterprises. Secondly, the proportion of inter-provincial of investment has gradually increased. Inter-provincial of investment increases from 856 million yuan in 2000 to 28.808 billion yuan in 2021, and the proportion increases from 11.59% to 31.06%. The amount of financing is "high in the east and low in the west". Thirdly, Fuzhou has always been the preferred city for corporate investment, but with the passage of time, Xiamen, Quanzhou, and other hubs continue to emerge, agglomerating to form the Fuzhou-Xiamen-Quan Corridor at its core. Fourthly, among the influencing factors, policies and the development environment of informatization have a significant role in promoting the investment and financing connection of digital economy enterprises, and the influence of geographical distance on the investment and financing connection of digital industry is gradually weakened. Finally, combined with the spatiotemporal evolution of the development of the digital industry in Fujian and its influencing factors, the paper puts forward policy suggestions, in order to provide scientific support for the construction of "Digital Fujian" and the sustained and healthy development of the digital economy in Fujian.
