为探究数字技术深化如何助力我国实现经济效率变革和高质量发展,本文构建能够反映数字技术质量和数字技术难度的数字技术深度指标,将其引入质量阶梯模型,从理论上揭示数字技术深化对生产率的影响效应与内在机制,并进一步结合2008-2020... 为探究数字技术深化如何助力我国实现经济效率变革和高质量发展,本文构建能够反映数字技术质量和数字技术难度的数字技术深度指标,将其引入质量阶梯模型,从理论上揭示数字技术深化对生产率的影响效应与内在机制,并进一步结合2008-2020年数字专利数据进行实证检验。研究表明:数字技术深化增强了数字技术专业化水平,有利于提升地区生产率;但是也加大了数字技术应用转化的难度,遮掩了部分促进效果。总体而言,数字技术深化对地区生产率具有促进作用,该效应在中西部地区和数字技术多样化地区尤为显著。进一步研究发现,地区研发水平、教育水平和劳动力素质能够正向调节数字技术深化的遮掩效应,是数字技术深化作用发挥的重要影响因素。 展开更多

Recent technological change and the economic upheaval it has produced are coded by social meanings. Cultural codes not only trigger technological and economic changes, but also provide pathways to control them, allowing the dem- ocratic practices of independent journalism to be sustained in new forms. Even as they successfully defend their professional ethics, however, journalists experience them as vulnerable to subversion in the face of technological and economic change. Indeed, independent journalists and the social groups who support them often feel as if they are losing the struggle for autonomy. Just as current anxieties have been triggered by computerization and digital news, so were earlier crises of journalism linked to technological shifts that demanded new forms of economic organization. Digital production has created extraordinary organizational upheaval and economic strain. At the same time, critical confrontations with digital production have trig- gered innovative organizational forms that allow new technologies to sustain, rather than undermine, the democratic culture and institution of news production. If news producers are making efforts to adapt professional journalism to the digital age while maintaining journalistic civil values, there are parallel adaptations from the digital side: digital journalism becoming more like professional journalism. 展开更多
