Why false value outputs as empty string?

Question

print "Result: " . (0 == 1); # Result:
print "Result: " . (1 == 1); # Result: 1

Why does perl output an empty string for a false value and not 0?

Because in Perl, the false value returned by many operators and builtins is a special value that is 0 in a numeric context and '' in a string context.
