Disclosed in the present invention are a digital nucleic acid amplification testing method and an integrated detection system based on CRISPR-Cas technology. The integrated detection system comprises an integrated reaction chip, a temperature control module, a light source and an optical signal detector. The method comprises: uniformly dividing a nucleic acid amplification reagent into amplification micro-droplets, then mixing the amplification micro-droplets after digital nucleic acid amplification with detection micro-droplets containing CRISPR-Cas detection reagent to perform a CRISPR reaction, and when the reaction is finished, detecting an optical signal to realize high-specificity testing of a target object, and the concentration or copy number of nucleic acid molecules in a sample to be tested is also obtained, and high-sensitivity absolute quantitative testing of a target object is realized.
