摘要: 基于黑龙江省生猪养殖现状,运用柯布-道格拉斯生产函数,选取生猪养殖的投入产出指标,建立生猪规模经济效益模型。通过实证分析得出结论:黑龙江省生猪养殖数量是影响规模经济效益的重要因素。生猪养殖规模在100头以上时,会实现规模报酬递增。建议从合理规划、政策扶持、加强服务等方面提高黑龙江省生猪养殖规模经济效益。

Abstract: Based on the status of pig farming in Heilongjiang Province, using Cobb- Douglas production function, input and output indicators of pig farming were selected, and scale economies models were built. Through empirical analysis, it could be concluded that the number of breeding pigs in Heilongjiang Province was an important factor affecting scale economies. When the scale of pig farming above 100 or more, increasing returns would be achieved. Suggestions were put up from rational planning, policy support, strengthening services in order to improve scale economies of pig farming in Heilongjiang Province.
