Kōda Rohan’s creative career of more than 60 years is closely connected with the process of Japan’s modernization. In particular，his observation of Japan’s economic life not only makes his literary works have a “pragmatic” style，but also provides a steady stream of vitality for his creation. The craftsman themed novels he created provided a ideological foundation for the integration of industrial civilization into Japanese society，and the rich and diverse youth literature inspired the economic thinking of the lower class workers. His Effort Theory and Self-cultivation Theory that explore labor capital relations are still regarded as standards. However，the excessive emphasis on the grand economic narrative and the close adherence to the national strong discourse make it difficult for him to objectively examine the real history. When the world was in decline，his incompleteness and firmness made his economic proposition radical and extreme，his value orientation distorted，his “industrial literature” gradually lost its literary consciousness，and it was difficult to establish a spiritual belief that made readers feel the same.
