Taking agricultural research institutions as research objects, through analysis of agricultural science and technology human resources, agricultural science and technology financial resources in the basic research, applied research and experimental development of the three different stages of scientific and technological activities; in agronomy, forestry, aquaculture, animal husbandry and veterinary, etc. The possible changes in agricultural science and technology output caused by the distribution among different subject areas, using the nuclear density estimation function system to measure the dynamic evolution of financial resources in different stages of science and technology activities from 2005 to 2015. The results show that agronomy has a dominant position in various disciplines. The overall investment in agricultural science and technology resources has been greatly improved at each stage. The experimental development has the largest increase, but the regional differences are obvious. The eastern region and the central region have grown significantly. The northeast region and the western region showed a negative growth trend; the basic research stage showed an overall upward trend, and the northeast region had a greater impact on science and technology investment; the overall difference in the applied research phase and regional and nationwide showed negative growth.
