在考虑空间作用异质性的基础上,采用地理加权回归实证分析了中国农业科研投资的生产率效应,为优化农业科研投资配置提供参考。结果表明,科研投资对部分农业大省的生产率拉动作用明显,西部省份的科研投资水平较低制约了其生产率效应的发挥。结合中国农业重心"北上""西进"的实际情况,要注重加强东北部和中西部地区的农业科研投资。
Based on spatial heterogeneity of agricultural productivity,productivity growth effect of agricultural research expenditure was empirically analyzed using geographical weighted regression model to provide reference for optimizing agricultural research expenditure allocations.The results showed that the effects of agricultural research esxpenditure on agriculture productivity growth in some agricultural provinces were relatively better than that in Western provinces whose expenditure level was lower.Considering the actuality that the focuses of agricultural production in China are North and West,the proposal was put forward that agricultural research expenditure in North-Easter agricultural provinces and mid-western area should be enhanced.
