摘要
基于1998—2015年省级面板数据,利用空间面板模型对省域农业科研投资增产效应的空间溢出性进行了实证分析。结果表明:农业科研投资和粮食产量均存在着较强的空间集聚性;农业科研投资具有明显的空间溢出和扩散效应,但对粮食产量却没有显著的影响。为了有效挖掘农业科研投资增产的潜力,提出了重构农业科研投资布局、调整优化财政支农支出结构以及强化农业科研成果转化能力等对策建议。
Based on the 1998--2015 provincial panel data, the spatial spillover on the effect of agricultural research investment＇ support for grain production is empirically analyzed by spatial panel model in this study. The results showed that there exists strong spatial agglomeration between agricultural research investment and grain production. Although the agricultural research investment had significant spatial spillover and diffusion effects,it had not great influence on the grain production. In order to further tap the potential of agricultural research investment to increase grain production, we should reconstruct the layout of agricultural research investment, optimize the structure of financial support for agriculture and strengthen the transformation ability of agricultural scientific research achievements.
