什么是规模报酬 a The scale ofproduction a If a firm were to double all of its inputs-sometimes it could do in the long run could it double its output? Or will output more than double or less than double? We can distinguish three possible situations Constant returns to scale Increasing returns to scale o Decreasing returns to scale

一、什么是规模报酬 ▪ The scale of production ▪ If a firm were to double all of its inputs—sometimes it could do in the long run—could it double its output? Or will output more than double or less than double? We can distinguish three possible situations: ▪ l Constant returns to scale ▪ l Increasing returns to scale ▪ l Decreasing returns to scale
