LEONTIEF TECHNOLOGY AND THE LOCATION OF THE FIRM IN A WEBER TRIANGLE–SPECIFIC LOCALIZATION THEOREMS*
研究了在里昂惕夫技术（固定投入产出系数）的特殊情形下，企业选址的一般定理得到确认和加强，提出了三角形空间中企业选址的充分条件，并分析了投入替代对选址的影响。
ABSTRACT In special cases of the Leontief technology's constant input‐output coefficients, the general localization theorem that an interior location is a global optimum if every input or market vertex is not a local optimum [Kusumoto (1984)] is confirmed and strengthened. Sufficient conditions are proposed for the portion of a triangular space in which the firm will locate. Finally, it is shown that, if input substitution is permitted and its effects dominate spatial effects, the firm's total cost function will be monotone, as well as concave, hence the vertex is a global optimum if it is a local optimum.
