摘要
鲜有文献运用空间计量模型分析中国农业技术的空间溢出效应。在测算中国28个省1986-2010年农产品技术相似矩阵和农业技术溢出量的基础上,运用空间面板数据模型分析了中国农业技术的空间溢出效应。研究结论表明:中国的农业生产存在空间相关性,这种空间相关性在农业技术相似省份间表现更为明显;省份间农业技术溢出对各省农业生产存在正效应,农业技术省际溢出系数约为0.25,大于各省人均农业科技投入存量系数(约0.12);对经过多维标度法聚类后的三类农业技术相似省份的进一步分析表明,省份间农业技术越相似,省际技术溢出效应越大。
Few studies focou on the effects of spillover of agricultural technology using the approch of spatial econometrics. Based on measurement of the matrix of similarity of agricultural products and the stock of technology spillover, we analyze the effects upon which agricultural technology spillover have to product. We reach conclusions as follows ： there is spatial correlation for agricultural production in China, and the spatial correlation become more significant when one province is more similar to the other provinces in agricultural technology. Agricultural technology spillover between provinces have positive effects on the production of agriculture, and the estimated coefficient lies in 0.25, bigger than the coefficient of the stock of research of own（0.12）. Using multi - dimensional scaling, we get three clusters of provinces in which the technology is similar. The effects of technology spillover within the clusters are greater than that between them.
