Agricultural Productivity Revisited
构建了农业总产出、资本、劳动和中间投入的指数，测算全要素生产率，并比较投入增长与生产率增长对经济增长的贡献，凸显生产率增长在农业中的关键作用。
Abstract This paper describes production accounts for agriculture. Output is defined as gross production leaving the farm as opposed to real value added. Inputs are not limited to capital and labor but include intermediate inputs as well. We derive index numbers of gross output, capital, labor, and intermediate inputs. These data are used to construct indexes of total factor productivity. We then compare the contributions of input growth and productivity growth to economic growth. The important role of productivity growth in agriculture becomes immediately apparent.
