我国粮食生产效率与可持续发展：1978～2004

China＇ s Food Production and Sustainable Development： 1978-2004

改革开放以来，我国总体粮食生产的土地节约型技术进步类型，与四种粮食生产的劳动节约型技术进步类型并不一致，这种“悖论”源于对粮食生产中劳动力投入的不同理解。总体上看，我国粮食生产的劳动生产率指数高于土地生产率指数．粮食生产总体采取的是劳动生产率提高的技术进步类型。我国未来粮食的持续性增产有赖于促使粮食生产技术进步、尤其是劳动生产率提高的技术进步，而这点是与粮食生产中劳动力的持续流转紧密相关的．

Since the reform and openness of China, the land-saving technological progress type of food production did not coincide with the four kinds of labor-saving technological progress, which is originated from the different understandings of labor input in food production. As a whole, the number of labor productivity index is higher than the figure of land productivity index of China food production, and the food production depends on the technological progress. The persistence of food production increasing in China. will depend on the technological progress of food production in future, especially promoted by the improving labor productivity, which is closely related to the continuing labor circulation in food producing.
