政治经济学第三单元参考答案
第三单元作业参考答案一、产业资本循环的三个阶段和三种职能形式是什么？1、产业资本循环的三个阶段是：购买阶段、生产阶段和售卖阶段。
2、三种职能形式是：货币资本、生产资本和商品资本二、产业资本循环为什么是三种循环形式的统一？1、产业资本循环的概念：产业资本一次经过三个阶段，采取三种职能形式，使价值得到增值，最后又回到出发点的运动。
2、资本家对剩余价值的追求是无止境的，因此资本必须周而复始地进行循环。
产业资本的三种职能形式都不断地经过三个阶段，进行着各自的循环运动，因此产业资本有三种循环形式：货币资本的循环、生产资本的循环、商品资本的循环。
3、在现实的产业资本循环运动中，产业资本的三种循环形式并不是各自单独循环、孤立存在的，而是处在所有三种循环之中。
每一种循环形式都以其他循环形式为前提，而且每一种循环形式的进行，也必然包含其他循环形式在内。
所以，产业资本的循环是三种循环形式的有机统一。
三、实现产业资本连续循环的条件是什么？1、产业资本循环的概念：2、实现产业资本连续循环的条件是：第一，产业资本的三种职能形式必须按一定的比例在空间上同时并存（即空间上的并存性）。
第二，产业资本三种循环形式必须具有空间上的继起性。
四、影响资本周转速度的因素是什么？1、周而复始的资本循环就是资本的周转。
2、影响资本周转速度的因素有：第一，资本周转时间——包括生产时间和流通时间——的长短，第二，生产资本的构成，即固定资本和流动资本的比例。
五、固定资本何为流动资本的划分同不变资本和可变资本的划分有何区别？1、划分固定资本和流动资本的依据是资本的价值周转方式不同。
2、划分不变资本和可变资本的依据是根据预付资本在价值增值过程中的不同作用。
六、怎样考察预付资本的总周转速度？1、预付资本的总周转，是它的不同组成部分的平均周转。
2、预付资本总周转的计算公式：固定资本周转价值总额+流动资本周转价值总额预付资本总周转速度（次数）=预付资本总额七、资本周转速度对剩余价值生产有什么影响？资本周转速度的快慢对剩余价值的生产和实现有重大的影响，主要表现在以下几方面：第一，加快资本周转速度，可以节约预付资本，特别是节约预付资本中的流动资本。

Now study the sad one a little closer. Try to pin down the exact quality of its sadness. Is it pessimistically sad or resignedly sad; is it fatefully sad or smilingly sad?可能的话，你不妨听听巴赫的《平均律钢琴曲集》中的48个赋格主题。
