问题如下：
A firm that increases its quantity produced without any change in per-unit cost is experiencing:
选项：
A.economies of scale.
B.diseconomies of scale.
C.constant returns to scale.
解释：
C is correct.
Output increases in the same proportion as input increases occur at constant returns to scale.
考点：规模报酬不变
解析：题中所属商量增加的同时，单位成本不变，那就是表明规模报酬不变。所以选C
如果是增加产量同时单位成本减少，那才是规模经济。
C提到的情况，是指完全竞争市场么。

NO.PZ2016010802000050 b为何不正确呢，产量增加，价格未变，说明总成本增加，这种情况是规模不经济呀。
