Abstract: This paper gives the general relationship between production function and cost function,and proves that there exists a homogeneous correspondence,that is a firm’s cost-maximizing decicsion transforms a homogeneous production function into a homogeneous cost function while a homogeneous cost function results certainly from a homogeneous production function.

Key words: production fuction, cost function, homogeneous function, cost maximization
