摘　　要：从数字产业化和产业数字化两个维度分析数字科技驱动经济社会发展质量变革、效率变革、动力变革的机制。以长江经济带44个城市为样本,利用熵权法测算其数字科技发展水平,构建面板向量自回归(PVAR)模型,实证检验2004-2019年样本城市数字科技驱动转型升级情况。结果表明:数字科技与经济转型升级存在发展惯性,且数字科技是影响地区经济转型升级的重要因素,其驱动作用具有一定区域异质性,具体表现为对中游城市具有稳定的促进作用,对上游、下游城市经济转型升级的引擎作用未显现,短期内甚至产生抑制效应。为提升数字科技发展水平、发挥其驱动地区经济转型升级的重要作用,长江经济带要继续深化数字产业化、强化产业数字化、优化人才战略体系、细化区域发展策略。From the two dimensions of digital industrialization and industrial digitization,this paper explored the mechanism of quality change,efficiency change and power change promoted by digital technology in the economic and social development.In the paper,44 cities in the Yangtze River Economic Belt were selected as samples.On the basis of measuring the development level of digital technology by using entropy weight method,this paper empirically tested the situation of transformation and upgrading driven by digital technology in sample cities from 2004 to 2019 by constructing PVAR model.The results show that digital technology and economic transformation and upgrading have inertia,and digital technology is an important factor that affect regional economic transformation and upgrading.Its driving effect has certain regional heterogeneity,and it has a stable promoting effect on the midstream cities,but the engine effect on the economic transformation and upgrading of the upstream and downstream cities is not obvious,and even has a short-term inhibiting effect.Therefore,in order to enhance the level of digital technology and give full play to its role in driving regional economic transformation and upgrading,it is necessary to deepen digital industrialization,strengthen industrial digitization,optimize the talent strategic system,and refine the regional development strategy.
