帮你顶一下，楼下的继续回答，不过lz你把学科和整个句子贴出来岂不是更好？

谢谢。 说的有道理，文章是在估计Cobb-Douglas production function.

关于第一个是这样的：Output (Y) is constructed as plant sales (total value of shipments in the LRD) plus changes in the value of inventories for finished goods and work-in-progress.
第二个：Labor input (L) is defined as production-worker-equivalent man-hours—
that is, the product of production-worker man-hours, and the ratio of total
wages and salaries to production-worker wages.

第一个是， 每个工厂的销售量
第二个是， 生产工人的工作量（小时）* 每小时生产工人的工资 =》要花多少钱来代替这个产能。。。
