数字经济驱动宏观经济治理体系完善的理论逻辑与政策实践——基于马克思社会再生产理论的分析

Theoretical Logic and Policy Practice of Digital Economy Driving the Improve-ment of Macroeconomic Governance System——An Analysis Based on Marx’s Theory of Social Reproduction

数字经济发展是供给—需求实现总量平衡、结构适配、质量协同升级的关键连接点。揭示数字经济下宏观经济的运行机制,研究适应数字经济的宏观经济治理体系,对于促进数字经济和实体经济深度融合有重要启示。基于马克思社会再生产理论,构建包含数字生产及其下游部门的四部类再生产模型。研究发现:数字要素部门的资本积累对总产出增长有棘轮效应;一旦发生负向的需求冲击,数字经济将有助于宏观经济保持韧性,避免短期总产出大幅减少;数字要素部门的相对独占性将可能削弱扩张性需求管理的政策效果。面对数字经济兴起对社会生产组织方式和运行模式的冲击,中国展开了完善宏观经济治理体系的政策实践。具体包括:发挥数字经济的高能增长极作用,协同推进需求总量调控与供给体系质量提升;释放数字经济的创新驱动力,构建适应数字技术创新周期的宏观资源筹措、调峰和配置机制;激活数字经济的要素黏合效应,形成宏观经济政策与产业、区域等政策紧密配合的宏观治理体系。

Summary The research question of how the digital economy can effectively promote changes in the organizational and institutional arrangements of social production and empower the modernization of governance systems and capabilities at all levels holds significant research value.Currently,there is little research on the digital economy’s role in driving macroeconomic governance changes.The digital sector and the physical sector are interconnected within the physical value chain and the innovation value chain,with unique exchange and competition relationships.In the macroeconomy,the digital sector is susceptible to output fluctuations during investment and financing exposure periods or industry cycle nodes,leading to broader economic fluctuations,which may render traditional macroeconomic control measures ineffective.The distinctive operational rules of the digital economy necessitate timely updates to macroeconomic governance and innovative implementation of macroeconomic policies in terms of ideas,methods,and means.This article uses Marx’s theory of social reproduction as a foundation to construct a four-part reproduction model that includes digital production and its downstream sectors.It deduces the macroeconomic operation mode,policy tools,and governance system under the digital economy.The research findings include:1)Increased capital accumulation in the digital factor production sector drives growth in other sectors and overall output.2)Faster technological progress in the digital consumer goods production sector accelerates capital accumulation in the digital factor sector,promoting total output growth.3)Capital accumulation in the digital factor sector has a ratchet effect on total output growth,indicating that even a one-time increase in capital accumulation can continue to provide a positive supply shock to the macroeconomy.4)In the event of a negative demand shock,the digital factor sector increases research and development investment and accelerates technological breakthroughs to avoid a decline in profit margins,helping to maintain macroeconomic resilience and avoid drastic fluctuations in short-term total output.5)The relative exclusivity of the digital elements sector may weaken the policy effectiveness of expansionary demand management.The conclusion implies that in the digital economy,both initial demand shocks and demand policies aimed at rebalancing struggle to maximize short-term equilibrium changes.Therefore,macroeconomic rebalancing and long-term growth rely more on supply expansion or structured demand management policies combined with supply,and traditional regulatory measures would be partially ineffective.In recent years,China has implemented a series of institutional innovations in fiscal and monetary policies,coordinating with other policies,creating a new model for macroeconomic governance under the high-level socialist market economy system.This governance system fully considers the universal characteristics of the overall economic operation under the digital economy,aligning with the new characteristics of the macroeconomic rebalancing mechanism.It will continue to innovate and improve with the deepening development of the digital economy.Key points of this governance system include:1)Maximizing the high-energy growth potential of the digital economy,synergistically promoting the regulation of total demand and the improvement of supply quality.2)Unleashing the innovation-driven force of the digital economy,constructing a macro-resource mobilization,peak-adjustment,and allocation mechanism adapted to the cycle of digital technological innovations.3)Forming a macro-governance system where macroeconomic policy is closely coordinated with industrial,regional,and other policies。
