江苏省水稻生产投入要素及影响因素实证研究

以江苏省最主要的粮食作物水稻为例，按照2004年分县纯收入水平，以该省22个县的354户水稻种植户2005年横截面数据为样本，运用扩展的C—D生产函数，就投入要素及品种认知、农业生产决策者个人特征等影响因素对水稻生产的作用进行了研究。估计结果显示：目前土地仍是影响江苏省水稻产出的最主要因素，化肥在水稻生产上仍发挥着重要作用。随着水稻良种良法配套栽培的推广，农户水稻品种认知对水稻生产的重要性得到显现。鉴于耕地灌溉条件对水稻生产的影响非常明显，政府应加大对农田水利设施的建设投入。

Empirical Study on Input Factors and Influence Factors of Rice Production in Jiangsu Province

The most primary food crop in Jiangsu is rice.Based on the expanded C-D production function,this paper empirically analyses the effects of input factors and influence factors including the variety cognition and the individual characteristic of agricultural production decision-maker on rice production. From the micro-household perspective,354 cross-sectional household cases in 22 counties of the year 2005 are selected for this analysis. The estimate result indicates that nowadays the cultivated land is the most important factor influencing rice production in Jiangsu and the chemical fertilizer plays an important role in rice production. Along with the cooperation of the improved rice variety and the good planting method,the importance of the rice variety cognition of peasant households to rice production are more and more evident.Because the condition of farming irrigation obviously influences the rice production,the government must enlarge the investment on farmland water conservancy.
