The invention discloses a fuzzy entropy space clustering analysis method based on orderly information entropy, comprising the following steps: S1, inputting a standardized matrix, and letting an integer i=1; S2, assigning an ith value corresponding to a relationship set D to a fuzzy entropy space parameter, and initializing intermediate sets A and C; S3, letting an intermediate set B be empty; S4, if R(xj, xk)>=lambda, deciding that B=B union {xj} and A=A\{xj}; S5, if R(xj, xk)>=lambda, deciding that B=B union {xs} and A=A\{xs}, or going to S6; S6, letting C=C union {B}, and letting an integer i+1 assign a value to i; repeating the steps S2 to S6 until the integer i is equal to the size m of the relationship set D; S7, if A is empty, deciding that X(lambda)=C, and calculating the orderly information entropy at the moment; S8, if HP(min)=min{X(lambda)}, deciding that min=lambda and going to S9, or going to S2; and S9, outputting an optimal granularity level.
