The present invention belongs to the biomedicine field and specifically concerns an enzyme-degradable polymer and the application thereof. To solve the problem of low sensitivity of the existing assay reagents, the present invention provides an enzyme-degradable polymer and the related application of the polymer. The present invention also provides hydrogels, nano-particles, fluorescent dye-labeled enzyme substrates and kits (packages) for detection or activity-analysis of biological enzymes based on the enzyme-degradable polymer. The formula of the enzyme-degradable polymer is P
