我国生猪主产省与大中城市大规模生猪生产比较优势分析

Analysis on Comparative Advantage of Large-scale Pig Production in Major Production Province and Metropolis

运用概率优势模型,对主产省和大中城市在大规模生猪生产方面的地区优势进行比较分析。结果显示:与主产省相比,大中城市整体上在大规模生猪生产方面已不具备优势,东部沿海地区的主产省正逐渐丧失优势,东北和西南地区的主产省的优势逐渐显现;多数大中城市的大规模生猪生产在人工成本上处于劣势,但在技术水平上仍保持相当优势,北京、上海等大都市相比其他大中城市仍具有一定的大规模生猪生产优势,这主要得益于其先进的技术水平和政策扶持。

This paper uses the stochastic dominance model to analyze the comparative advantage of large-scale pig production in major pig pro- duction provinces and metropolises. The results show as follows：compared with major pig production provinces,the metropolises as a whole don＇t have the advantage in large-scale pig production, and major production provinces along the eastern seaboard are losing advantages gradually; ma- jor pig production provinces in the northeast and southwest have already presented their advantages gradually; most of the metropolises are dis- advantaged in labor cost of large-scale pig production,hut are advantaged in technology;the metropolises such as Beijing and Shanghai maintain some advantages, which mainly benefit from advanced technology and policy supporting.
