Abstract: There are obvious differences among different sizes of enterprises in technological innovation input and product quality, thus the impact of technological innovation input on product quality may vary with the enterprise sizes. It is of great significance to explore this question. Based on an empirical study with a manufacturing enterprises survey, some characteristics are identified: The impact of technological innovation input on product quality of small and medium enterprises is more significant, while the large enterprises are not. It reflects that small and medium enterprises have late-moveradvantages over the large ones. It is suggested that the government should guarantee the fund supply for small and medium enterprises’ technological innovation, provide platforms aimed at the research and development of generic technologies, and guide to build a system with thecombination of production, study and research. Moreover, the government should also cultivate technological intermediaries to provide technological services, thus promote the effect of technology innovation input on quality upgrading of small and medium enterprises.
