The Alberta hog industry problem of the 1960s: its definition and resolution
研究了20世纪60年代加拿大西部生猪产业因生产过剩和营销问题陷入困境，随后20年通过农民、政府和农业专家合作，重新定义问题并重塑产业，最终发展出可行的猪肉产业。
ABSTRACT The hog industry in Western Canada in 1960s was in a state of turmoil associated with a vague, poorly understood production and marketing problem. Hog production was largely a supplementary farm activity producing an overfat product increasingly shunned by consumers. The structure, and also probably the existence, of the industry was in question. During the following 20 years, the industry changed fundamentally as various groups achieved a better definition and understanding of the problem. A reshaping of the industry was carried out by farmers, the Provincial Government, and a variety of agricultural professionals concerned with industry structure, emerging pork markets, physical characteristics of the product, and creation of a policy environment that provided incentives for output and productivity growth. The outcome has been the development of a viable pork industry in the Province (in spite of some past and continuing hindrances to industry growth) that has substantially solved the problem.
