摘要：Australia has about 30,000 wheat growers comprising of 12,700 cropping specialists and the balance in combined grain and sheep enterprises. Despite the stability of grain grower numbers, productivity improvements have continued to drive increases in crop size. The Productivity Commission found that over the past three decades the cropping industry has shown the largest productivity gains (3.3 per cent a year) within agriculture. Productivity gains in cropping have also outstripped the economy wide productivity increases over the past thirty years.
