| 摘 要： | 运用1986～2005年的分省数据分别估计了全国及八大地区的畜牧业生产函数，并在此基础上分析了科研投资对畜牧业经济增长所作的贡献．结果表明，全国及各地区的畜牧业经济在过去的20多年里保持了持续增长的势头，但畜牧业科研投资的增长表现较为复杂．部分地区的畜牧业科研投资在某些年份还有所下降．同时也发现科研投资对全国及各地区畜牧业经济增长所作的贡献存在较大差异，其中东南区科研投资的贡献最大，达到了66．4％，西北二区的最小，仅为4．4％．

| Abstract: | Based on the statistic data of provinces in China from 1986 to 2005, the husbandry production functions of the nation and eight regions were estimated. In the paper, the contribution of R＆D to the husbandry growth was calculated. It was showed that, in the past 20 years, the husbandry had maintained sustained growth momentum, but the growth of R＆D investment in the husbandry by region were complex. R＆D investment of some regions in the husbandry in some years had even declined. It was also indicated that R＆D investment＇s contribution areas of China. The contribution of Southeast to the husbandry＇s growth were great different in different China was highest, up to 66.4 percent, while the region 2 of the Northwest China was lowest , only 4. 4 percent. |
