本文通过对中国大中型企业的R&D投入影响因素进行分析，探讨其技术状况。分析采用了国际贸易、FDI、政府R&D投入和企业规模四个影响因素，首先对方程的稳定性进行检验，然后进行回归分析，并进一步结合大中型企业的其它科技统计指标进行讨论。本文的分析得出大中型企业的整体技术还和国际先进水平有较大的差距，且两极分化现象明显，对大多数企业而言，当务之急是建立研发体系，尽快培养技术吸收能力。

The technological status in quo of Chinese large and medium-sized corporations is investigated by analyzing the affecting factors of their R&D investment. The four factors concerning international trade, Foreign Direct Investment (FDI), R&D investment of the government, and the total size of corporations are identified. At first, the instability of parameters and validity of model are checked, and then regression analysis is carried out. By analyzing the technological status in quo, other technical indicators are also applied in combination with regression results. The results show that the technological gap between Chinese corporations and the international level is still notable, besides the Chinese corporations per se have also been greatly polarized in technical levels. The first imperative for most Chinese corporations is building up their R&D system and cultivating their learning capability.
