I will finally consider development strategies for developing countries in this chapter. To do so, I ask readers to draw upon both the explanations provided thus far and their own common sense. I believe that much of economic theory is essentially a systematic organization of common sense. Therefore, I would like to rely on common sense rather than theory. First, we examine the differences between strategies for agricultural development and industrialization. I would like to show that there are more similarities than dissimilarities in the development strategies for these two industries. I would also like to show that effective development strategies should follow a specific sequence beginning with investments in intellectual and human capital for learning from abroad and proceeding to investments in infrastructure and physical capital.
