摘 要:以我国的最主要农作物水稻为例子,根据生产函数模型和资源配置优化原则,对我国稻区水稻生产的投入和产出进行综合分析。结果表明,目前农业生产在资源的利用上存在着极大的浪费。在化肥总用量上存在着地区间的不平衡;在劳动力使用方面,投入水平已经大大超过经济合理的界限。Rice is.the most important staple food in China.Using this vital crop as a case study.a production function is estimated based on time series and cross sectional data(by province).The estimated coefficients then are compared with the price ratio of output and input.The results indicate a larger misallocation of agricultural resources in rice production in China.In the fertilizer application,the poor allocation is mainly due to the unbalance of fertilizer distribution over regions.While in the labor use,a great overuse is revealed in all production regions,indicating the importance of shifting the labor force farming to non-farming sectors.
