The current research attempts to determine the degree to which three primary elements (Human, Structural, and relational capital) and intellectual capital are related to profitability of SMEs technological inventions in China’s Jiangsu province of as part of the country’s intellectualization process in the post-industrial era. The research utilizes data from 1,450 SME listings on the Shenzhen stock market between 2012 and 2020. The VAICTM model was used in this inquiry. Using PLS-SEM, the study evaluated four significant hypotheses. The research indicates that human and structural capital have a substantial meaningful correlation regarding SMEs success. The research also discovered a favorable association between human and structural capital and technological innovation in Jiangsu province throughout the post-industrial period. However, a strong negative correlation occurred between relational capital and the financial performance of small and medium-sized enterprises (SMEs). The research uncovered a substantial positive relationship between the technological innovation of SMEs and their financial success. The link between intellectual capital (HC, SC, and RC) and company performance was shown to be mediated and moderated by technological innovation. According to the findings, technical innovation considerably moderates the link between Human Capital and firm performance. The research indicated that Technical Innovation (TI) moderates the association between Structural Capital (RC) and firm performance. In contrast, Technical Innovation (TI) does not alter the association between Relational Capital (RC) and firm success in a substantial way.
