The productivity theory proposed by Marx, alongside the notion of common prosperity, serve as a robust theoretical foundation for an innovative paradigm of productive forces and spiritual life. A discernible logical interconnection exists between the two dimensions: the new productive forces furnish essential material support for spiritual life, while the pursuit towards common prosperity within this realm serves as a driving force for the advancement of new productive forces. The empowerment of spiritual life through new productive forces is firmly anchored in a people-centered value orientation. By spearheading high-caliber development through technological innovation, adhering to principles of sustainable growth, and fostering an innovative talent pool, the material foundation necessary for achieving common prosperity in spiritual life could be solidified. The approach will also help to establish a favorable ecological environment conducive to such prosperity and facilitate the realization of comprehensive human freedom and development.
