摘　　要：近年来,数字经济快速发展,已成为提升创新能力、增加创新产出的重要选择。知识生产是创新产出的主要形式,探究数字经济对知识生产的影响和作用机制对实施创新驱动发展战略具有重要意义。基于78个国家2015—2020年的面板数据,利用固定效应模型、中介效应模型、门槛效应模型分析数字经济对知识生产的影响。研究发现,数字经济能够显著促进知识生产,且该促进作用具有异质性。分学科看,相比于生化遗传学、材料科学、计算机科学、数学、能源科学领域,数字经济对知识生产的促进作用在环境科学领域表现得更明显;分国家经济发展水平看,相比于发展中国家,数字经济对知识生产的促进作用在数字资源禀赋更高的发达国家表现得更明显。研发投入在数字经济对知识生产的影响中发挥部分中介作用,研发投入水平的提升有助于数字经济对知识生产促进作用的发挥。随着数字经济发展水平和技术创新水平的提升,数字经济对知识生产的促进作用呈现边际效应递增的非线性变化特征。因此,应加强数字基础设施建设,搭建资源开放共享的协同创新平台,打造数字孪生系统,为数字经济赋能知识生产提供软硬件环境支撑;构建企业主导、高校与科研院所协同的知识生产专业人才培养体系,完善技术创新人才引进培育和激励评价机制,为数字经济赋能知识生产提供人才支撑;加强国家层面战略牵引,加大创新资源供给,为数字经济赋能知识生产提供政策支撑。In recent years,digital economy has been developed quickly,and it has become the important choice for us to improve capability for innovation and increase innovative output.Knowledge production is the important form of innovative output,and exploring the impact of digital economy on knowledge production and its mechanism is of great significance for implementing the strategy of innovation-driven development.Based on the panel data of 79 countries from 2015 to 2020,the authors take advantage of the model of fixed effect,intermediary effect,and threshold effect to analyze the impact of digital economy on knowledge production.It is found that digital economy can significantly promote knowledge production,and the promoting role of digital economy has the characteristic of heterogeneity.From the perspective of disciplines,comparing to the discipline of biochemical genetics,materials science,computer science,mathematics,and energy science,digital economy has the strongest promoting effect on knowledge production in the discipline of environmental science;and from the perspective of national economic development level,comparing to developing countries,digital economy has the strongest promoting effect on knowledge production in developed countries with higher digital resource endowment.R&D investment plays a partial intermediary role in the process of digital economy promoting knowledge production,and the increase of R&D investment is conducive to the role of digital economy in promoting knowledge production.With the improvement of digital economic development level and technological innovation level,the impact of digital economy on knowledge production demonstrates the characteristic of non-linear change with increasing marginal effect.So,we should,first,enhance digital infrastructure construction,establish the coordinated innovation platform with sharing resources,and establish digital twin system to provide digital economy with support of both software and hardware environment to empower knowledge production;second,w
