This chapter explores industrial soft power (ISP), tracing its origin to Joseph Nye’s concept. ISP is defined as an intangible capability rooted in the industrial economy, embodied in innovation, product quality, brand influence, and international rule-making, reflecting a nation’s industrial competitiveness and appeal. Core traits of ISP are outlined: leading, intangible, noncoercive, pervasive, and subtle. The chapter clarifies the mutually reinforcing relationship between ISP and industrial hard power (IHP), with IHP as the material foundation. A three-layer ISP structure is proposed: product reputation (surface), industrial values (core), and institutional rules (ultimate manifestation), explaining their operational mechanism of gradual influence. Sectoral and enterprise-level ISP are also analyzed. The findings emphasize that ISP is core to national industrial competitiveness, requiring the transformation of cultural resources into recognized influence.
