Abstract
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.
