西澳農業之生產力成長分析

An Analysis of Productivity Growth in Western Australian Agriculture

本文分析1977至2000年西澳大面積農業之生產力成長，利用一種無參數法，我們估計西澳產業之總合投入、產出及總要素生產力（TFP），並與其他地區之結果相比較。結果指出：西澳農業之TFP年成長率為4.8%，高居全澳洲第二名，若就西澳農業之細產業別來看，作物產業之TFP年成長率為最高（7.1%）。文中亦發現：新技術之採用及移轉對西澳農業之TFP成長有正面效果。而西澳農部之研發投入亦對產業成長有顯著之影響。

This paper analyses the productivity growth of Western Australian broadacre agriculture for the period 1977/78 to 1999/00. The growth of aggregate outputs, inputs and total factor productivity (TFP) is estimated by applying a non-parametric approach and the productivity performance of WA agriculture is compared with that of other Australian states. The TFP growth in WA agriculture has been the second highest at 4.8 percent per annum. Within WA, among the broadly defined industry groups, the Crops industry has experienced the highest TFP growth of 7.1 percent per annum. The transfer and adoption of new technologies appear to have had a positive impact on the TFP growth of WA agriculture, besides the influence of seasonal conditions. Research and development (R&D) contributions of the Department of Agriculture Western Australia appear to have significantly influenced the State’s agricultural productivity growth.
