单选题

Which of the following statements regarding economic and technological efficiency is most accurate?（）

A、 A productive process cannot be technologically efficient unless it is economically efficient.
B、 A technologically efficient production process uses the least amount of nonrenewable resources per unit of output.
C、 An economically efficient production process must be technologically efficient.

【正确答案】 C

【答案解析】

For a process to have the lowest production cost (be economically efficient) it must be technologically efficient. A process is technologically efficient if there is no other process that can produce the same output with less of at least one input and no more of the other inputs. A process that uses no less of any input and more of at least one input cannot be the lowest cost process and is, by definition, not technologically efficient.
