摘要
数字要素赋能已成为成渝地区双城经济圈产业升级的新途径,然而,目前缺乏对其在地理、经济和数字新型基础设施建设(以下简称“新基建”)等距离特征条件下数字化要素产生的空间效应的深入研究。为对成渝地区双城经济圈产业高质量发展在政策层面提供理论支持,从数字化创新环境、数字化创新技术、数字化人力资本、数字化劳动力、数字化资本等维度构建数字化要素评价体系,选取2012—2021年成渝地区双城经济圈的空间面板数据,基于地理、经济和数字新基建距离特征建立内生增长模型,运用空间计量模型实证分析成渝地区双城经济圈数字化要素和产业结构升级的关系。结果表明:成渝地区双城经济圈数字化要素和产业结构升级具有禀赋差异特征和时空集聚特征,且域间集聚差异在逐步扩大,3种距离特征下“成都+重庆”中心城市产业呈现出显著的生态化、集群化和丛林化特征,其他地区产业发展呈现出显著的专业化特征,对中心城市的空间依赖性越来越强。赋能产业结构升级方面,3种距离特征下,数字化要素对域内带来空间效应、对域外带来空间外溢效应,资源禀赋对域内具有空间促进作用、对域外具有空间抑制作用;在地理距离特征条件下,数字化技术创新对域外具有空间抑制作用;在数字新基建距离特征条件下,数字化人力资本具有空间抑制作用。此外,动态空间面板模型可以修正静态空间面板模型产生的过高空间估计误差。据此,建议加强成渝两极协同发展,形成两地产业的梯度化分工格局,实现成渝“双核”驱动相邻区域发展。
Empowering digital elements has become a new way for the industrial upgrading in the Chengdu-Chongqing Economic Circle.However,there is currently a lack of in-depth research on the spatial effects generated by the digital elements under the distance characteristics such as geography,economy,and digital new infrastructure construction(hereinafter referred to as"new infrastructure").To provide theoretical support for the high-quality development of industries in the Chengdu-Chongqing Economic Circle at the policy level,a digital element evaluation system is constructed from the dimensions of digital innovation environment,digital innovation technology,digital human capital,digital labor force,and digital capital.Using spatial panel data from the Chengdu-Chongqing Economic Circle from 2012 to 2021,the internal growth model based on the distance characteristics of geographical,economic,and digital new infrastructure is established,and a spatial econometric model is employed to empirically analyze the relationship between digital elements and industrial structure upgrading in the Chengdu-Chongqing Economic Circle.The results show that the digital elements and industrial structure upgrading of the Chengdu-Chongqing Economic Circle have endowment differences and spatiotemporal agglomeration characteristics,and the agglomeration difference between the regions is gradually expanding.Under the three distance characteristics,the central city industries of"Chengdu+Chongqing"show significant ecological,clustering,and forestation characteristics,while the industrial development in other regions shows significant specialization characteristics,with an increasing spatial dependence on the central cities of"Chengdu+Chongqing".In terms of empowering industrial structure upgrading,under three distance characteristics,digitalization should bring spatial effects within the domain and spatial spillover effects outside the domain,while resource endowment has a spatial promoting effect within the domain and a spatial inhibiting effect o
