| 以农业科研机构的财力资源投入为研究对象，基于2005—2014年31个省（自治区、直辖市）农业种植业、畜
牧业、渔业、农垦、农机化等5个行业的数据，运用基尼系数和核密度函数方法分析不同行业农业科技投入的地区差异
以及分布动态演变规律。结果表明：（1）各行业的科技财力资源投入水平均有所提升，种植业科技投入涨幅尤为明显。
（2）基尼系数结果显示，种植业科技财力资源投入总体差异呈现波动趋势，其中东北地区和中部地区投入差异明显，东
部地区呈现负增长趋势；畜牧业在全国范围内投入差距呈下降趋势；渔业投入整体态势平稳，各地区间差异不明显；
农垦农机科技投入存在明显区域差异，其中东部地区对科技投入总体差异的影响最大。（3）Kernel密度估计显示，各主
体间农业科技财力资源投入的总体水平不断提高，总体差异变化加剧，种植业与畜牧业所呈现的多极化态势呈现出缓
解的趋势。 |

| Based on the input of financial resources of agricultural scientific research institutions, this paper
uses Gini coefficient and kernel density function to analyze the regional differences and dynamic evolution
laws of the five industries of agricultural investment. Through the analysis of 31 provinces (cities, districts)
from 2005 to 2014 and the five industries of farming, animal husbandry, fishery, farmland and agricultural
machinery, the results are as follows:(1)The investment in agricultural science and technology resources in
each industry has increased in the research period, especially in the planting industry.(2)The Gini coefficient
results show that the overall difference in investment in the resources of the planting industry is fluctuating.
The difference between the northeast and central regions was obvious, and the eastern region showed negative
growth trend. Livestock industry in the country within the gap was a downward trend. The overall situation of
fishery investment was stable and the differences between different regions were not obvious. There are obvious
regional differences in the investment of agricultural mechanization technology, and the eastern region has
the greatest influence on the overall difference in technology input.(3)Kernel density estimation shows that theoverall level of investment in resources of agricultural science and technology in the main industry has been
increasing, and the change of the industry has been aggravated. The trend of multi-polarization presented by
planting industry and animal husbandry presents a trend of mitigation. |
