Abstract: This paper remeasured the level and rate of Chinese technological progress by applying growth function and generalized Solow residuals It built a state space model and used Kalman filtering to empirically analyze technical progress and imports rate of technological progress This study showed that: first, although the overall level of Chinas technology was growing, the rate fluctuated greatly, which indicated that the trend of technological progress was not yet stable; second, imports negatively affected technological progress, which was alleviated by reform and openness It could obstruct technological progress to some extent, but the impact of import trade on the rate of technological progress was still significantly positive
Key words: import , technological progress , growth function , state space model
摘要: 本文基于周方的“增长函数”,并借鉴“广义索罗余值”思想对中国技术进步水平和速率进行重新测度。在此基础上构建状态空间模型并利用卡尔曼滤波,实证分析进口贸易对技术进步和技术进步速率的影响。本文研究表明:第一,中国的技术水平虽然整体保持增长,但是速率波动很大,表明技术进步趋势尚不稳定;第二,进口贸易对技术进步呈现显著负向影响,改革开放虽然减轻了影响程度,却没有改变影响方向。可见进口贸易在一定程度上抑制了技术进步,但是进口贸易对技术进步速率的影响依然显著为正。
