Abstract: In accordance with the principles of the Report of the20th National Congress of CPC and the arrangements of the Central Economic Work Conferences in recent years，this paper reviews the adjustment and changes of demandoriented policies in Chinas economy，and explores the operational mechanism and structural evolution of the demand side based on quantitative analysis and verification of the changes of demandside synergies，and clarifies the interdependence and mutual promotion of internal and external demand under the new development paradigm This paper concludes that the main blockages on the demand side are： unequal income distribution，unreasonable consumption structure，lack of social security and relatively conservative consumption concept，demand imbalance under the traditional economic development model，bottlenecks in effective supply and deterioration of the world economic situation due to the sudden risky events，which are caused by the longterm accumulation of history and culture，the process of market economy after the reform and openingup，and also the wave of counterglobalization and the impact of unforeseen events boosted Therefore，it is suggested to take three approaches of boosting consumption demand，expanding investment demand and stablizing external demand to effectively dredge the blockage on the demand side，and finally achieve highquality and sustainable development of Chinas economy

摘要： 根据党的二十大报告精神和近年来中央经济工作会议部署，通过回顾中国经济需求导向政策的历史演进，并对需求侧协同关系变化进行量化分析和验证，以此探究需求侧运行机制与结构演变，阐明新发展格局下内外需相互依存、相互促进的关系。研究认为，当前需求侧所面临的主要堵点有：收入分配不平等、消费分布结构不合理、社会保障欠缺与消费观念相对保守、传统经济发展模式下的结构失衡、有效供给瓶颈制约以及突发风险事件情况下经济形势恶化等，产生原因有历史、文化传统长期积累所影响，有改革开放后市场经济运行过程所形成，也有逆全球化浪潮所助推以及突发事件冲击所叠加。因此，建议采取提振消费型需求、扩大投资型需求以及稳固外向型需求三条路径，从而有效疏通需求侧堵点，最终实现中国经济高质量可持续发展。
