摘　　要：为进一步厘清数据要素的宏观经济机理、分析与评估宏观经济政策推动数字经济发展的动态效应,秉承“新古典复兴”学派的逻辑,本文构建了包含网络平台主体的新凯恩斯动态随机一般均衡模型(DSGE模型),研究了货币政策、财政补贴政策与非数字人力资本投资冲击分别对消费增长、数据资本积累、总产出增长率和通货膨胀率等宏观变量的动态效应,并模拟研究了货币政策和财政补贴政策协调促进我国数字经济发展的效应。分析发现,网络平台对消费需求大数据的深度学习和及时反馈,提升了货币政策调控物价、拉动内需增长的效率,加速了数据资本积累并呈现出与非数字经济时代不同的特征;政府对网络平台研究与试验发展(R&D)项目的适度补贴可持续刺激消费增长,有利于改善市场配置效率、削弱商品价格上涨刚性、保持物价长期稳定;非数字人力资本投资是把双刃剑,能够推动经济增长,但会抑制数据资本积累;数字时代,科学协调财政补贴政策与货币政策可使我国宏观经济在增长路径上保持可持续性发展。In order to further clarify the macroeconomic mechanism of data factor, analyze and evaluate the dynamic effects of macroeconomic policies on digital economy development, adhering to the logic of the “neoclassical revival” school, this paper constructs a new Keynesian DSGE model including Internet platform agents. This paper studies the dynamic effects of monetary policy, fiscal subsidy policy and non-digital human capital investment impact on consumption growth, data capital accumulation, total output growth rate and inflation rate respectively. This paper also simulates the effects of monetary policy and fiscal subsidy policy coordination on the development of China’s digital economy. It is found that the deep learning and timely feedback of the Internet platform on consumer demand big data improves the efficiency of monetary policy in regulating prices, stimulating the growth of domestic demand, and accelerates the accumulation of data capital, which is different from that in the era of non-digital economy.Appropriate government subsidies for research and experimental development(R&D) projects on Internet platform can continuously stimulate consumption growth, improve market allocation efficiency, weaken the rigidity of commodity price rise and maintain long-term price stability.Non-digital human capital investment is a double-edged sword,which can promote economic growth,but restrains data capital accumulation.The scientific coordination of fiscal subsidy policy and monetary policy in the digital era enables China’s macro-economy to maintain sustainable development on the growth path.
