The fact is that the reliance on the country of R & D budget, which is indispensable for the technical development of the spatial information industry and the development of the industry, is very high. However, the actual analysis and evaluation of the outcome of the R & D investment including the spatial information industry is not actually done. It is a time when it is necessary to make a system for accurately measuring and evaluating the results of investment from a long-term perspective.
In this research, we aim to develop a dynamic model to evaluate the outcome of R & D investment of spatial information by using analysis method suitable for long-term analysis differentiated from existing research method. Specifically, we try to empirically analyze the relationship between the outcome of the internationally recognized thesis (SCI), which is a research result resulting from R & D investment of spatial information, using a dynamic model. We used System Dynamics(SD) for modeling and analyzing dynamic models to achieve the objectives of our research. The SD method is an analysis method suitable for quantitatively analyzing and simulating a dynamic model and the conventional analysis methodology is an approach from the viewpoint of other viewpoints. The conclusions derived through research execution are as follows.

1. It turned out that a total of eight R-feedback loops exist among the variables constituting the outcome of R & D investment of spatial information. In addition, it was found that continuous interaction occurred through the discovered feedback loop.
2. We modeled the dynamics model of spatial information R & D investment. For the constant values and initial values of each variable used for modeling, simulation was carried out using statistical data and deep interview materials. As a result, it is analyzed that the results of 149 SCI papers in 2016 will increase to 201 in 2025 if the R & D budget of spatial information continues to be invested like present.
3. Analysis was made that the increase in research results through changes in government 's R & D budget showed the effect in the shortest time. Increasing the ratio of R & D expenditure of spatial information from 8% to 24% or increasing the proportion of spatial information research expenditure of government R & D budget from 11% to 33%, shows the greatest research result and analysis It was done.
4. It is analyzed that research results are displayed high enough to shorten the time required for teaching engineers in the spatial information field. Currently, it is analyzed that it shows the greatest research result when shortening the education period of technicians taking about 5 years to 2 years.
5. In the case of technical feasibility and technology level, it does not have much effect on the increase of research performance. The higher the level of technological feasibility and technology, the slower the increase of the research result. That is, when the value of the variable of the initial level is high, it is limited to the amount of change that can change according to the change of time (when the initial level is 40%, the maximum change amount is 60%, the initial level is 70% , The maximum change amount is 30%), it was possible to learn through analysis showing the effect on the paper outcome is low.
