After World War II, international technology trade began to take shape and rapidly expansion, becoming a booster for promoting economic development in various countries and even the world. This article starts from the current situation of China"s technology trade and economic development, and uses cointegration and error correction models to empirically analyze the long-term equilibrium and short-term adjustment relationship between China"s technology trade and economic growth from 1985 to 2020. It suggests that technology trade balance has a negative impact on GDP growth rate in both the short and long term, but the long-term impact is greater than the short-term impact; There is a short-term reverse adjustment mechanism between the technology trade balance and GDP growth rate, but the adjustment intensity is relatively small.
