Science and technology are the primary productive forces, and technological innovation is particularly important for the development of technology companies. In order to better accumulate and apply technology capital, this paper descriptively analyzes the technology capital of private technology enterprises from the whole and various industries, and then explores the relationship between corporate equity structure and technology capital through modeling. The empirical analysis shows that there is a large difference in technical capital between different industries. There is no significant correlation between product competition and corporate technology capital. Equity concentration, equity checks and balances have a significant positive relationship with technology capital. Firm size has a significant negative impact on technology capital.
