:文章立足于循证科学的视角和方法，以“基于当前可得的最佳证据”为基本原则，沿着从理论驱动到数据驱动的经济学方法演化路径，对从前古典时期到现代经济学各个理论发展时期的经济学证据演化进行了梳理，构建了主要包括证据来源、证据生产、证据评价等环节的循证经济学全证据链框架。研究发现，循证科学的理念始终贯穿于经济学证据的演化历史之中；大数据时代的经济学“最佳证据”是一个广义、多源的各种最佳证据集合；大数据时代，经济学证据从理论驱动走向数据驱动，证据链得到优化升级，最终助推经济学研究范式的转变与循证经济学的发展。

Based on the perspective and method of evidence-based science, the article takes "based on the best available evidence" as the basic principle, along the path of evolution from theory-driven to data-driven economic methods, from the early classical period to modern economics. The evolution of evidence in the period of theoretical development was sorted out, and a full evidence chain framework of evidence-based economics including evidence source, evidence production and evidence evaluation was constructed. The study found that the concept of evidence-based science always runs through the evolutionary history of economic evidence; the "best evidence" of economics in the era of big data is a collection of the best evidence in a broad sense and multiple sources; the era of big data, the economy The evidence from the theoretical drive to the data drive, the evidence chain is optimized and upgraded, and finally promotes the transformation of economic research paradigm and the development of evidence-based economics.
