摘　　要：以信息通信技术(ICT)为基础的数字技术是当前有效配置生产要素,重塑产业结构的中坚力量。构建由ICT驱动的产业结构变迁模型,使用遗传算法对模型进行参数校准,探究数字经济赋能中国产业结构优化升级的内在机理。研究发现:由于ICT对第三产业全要素生产率(TFP)的贡献大于第二产业,ICT的扩散效应能驱动产业结构升级;由于ICT对第一产业TFP的贡献最小,家庭的消费结构呈现工业品和服务品的消费权重大于农产品,且服务品具有最大消费权重的特征,ICT的扩散效应和替代效应能共同驱动产业结构优化。进一步研究发现,与赋有“工业化”特征的地区相比,ICT对具有“服务化”倾向或特征地区的产业结构优化升级的驱动作用更显著。Based on information and communication technology(ICT), digital technology is the core force for effectively allocating production factors and reshaping industrial structure. This paper constructs an ICT driven industrial structure change model, uses genetic algorithm to calibrate the parameters of the model, and explores the internal mechanism of the digital economy promoting the optimization and upgrading of China’s industrial structure. It is found that since ICT contributes more to the total factor productivity(TFP) in the tertiary industry than in the secondary industry, the diffusion effect of ICT can drive the upgrading of industrial structure. As ICT has the smallest contribution to the TFP of the primary industry, the household consumption structure shows the characteristics that the consumption weight of industrial products and service products is higher than that of agricultural products, and the consumption weight of services is largest, the diffusion effect and substitution effect of ICT can jointly drive the optimization of industrial structure. Further study has found that ICT has a more significant driving effect on the optimization and upgrading of industrial structure in regions with “service-oriented” tendencies or characteristics, compared with regions with “industrialized” characteristics.
