Abstract: There are 5 main factors affecting the sustainable development of every country in the world, which are population, resource, environment, institution and technology. In this paper, a five-factor analysis model for the sustainable development of typical PRED system is generalized, and the importance extent of each factor is studied. The scale of regional population may speed up or slow down the regional economy development, and the situation of natural resources and geographical environments may also increase or reduce the difficulty of socio-economic development, but these 3 factors are not decisive, while only institution is the most important factor. The advanced science and technology will not be transformed into the real productivity without a good institutional system.
