【摘要】：文章基于我國(guó)23個(gè)省份在2004—2015年的面板數(shù)據(jù)建立了面板門檻模型,從農(nóng)民人均純收入視角對(duì)水稻生產(chǎn)中化肥產(chǎn)出彈性進(jìn)行了測(cè)算。結(jié)果表明,當(dāng)農(nóng)民人均純收入處于門檻值兩側(cè)時(shí),水稻生產(chǎn)中化肥產(chǎn)出彈性存在顯著性差異,當(dāng)農(nóng)民人均純收入高于3950.3元時(shí),水稻生產(chǎn)中化肥產(chǎn)出彈性會(huì)明顯提高。從考察末期窗口看,樣本中除云南省外,我國(guó)其他省份的農(nóng)民人均純收入均已跨過(guò)門檻值。
[Abstract]:Based on the panel data of 23 provinces in China from 2004 to 2015, a panel threshold model was established to measure the elasticity of fertilizer output in rice production from the perspective of farmers' per capita net income. When the per capita net income of farmers is on both sides of the threshold, there is a significant difference in the elasticity of fertilizer output in rice production, and when the per capita net income of farmers is higher than 3950.3 yuan. The elasticity of chemical fertilizer output will increase obviously in rice production. From the last period of investigation, the average net income of farmers in other provinces of China has passed the threshold value except Yunnan Province.

【正文快照】： 0引言作為作物產(chǎn)量和品質(zhì)的重要保證,化肥是糧食作物生長(zhǎng)的重要要素,對(duì)糧食作物增產(chǎn)的貢獻(xiàn)率相當(dāng)高。過(guò)去關(guān)于化肥在水稻生產(chǎn)中增產(chǎn)效應(yīng)的研究都是基于社會(huì)經(jīng)濟(jì)同質(zhì)性的假設(shè),利用線性回歸模型考察化肥對(duì)水稻增產(chǎn)的影響,而忽略了不同社會(huì)經(jīng)濟(jì)背景的差異,沒(méi)有重視農(nóng)民收入水平不，
