摘要
高科技产品出口有利于优化我国对外贸易结构,实现贸易强国目标。科研投入是促进科技创新、推动高科技产品出口的重要因素。利用主成分分析法,将反映科研投入情况的9个指标浓缩成一个综合指标;再以科研投入为解释变量,高科技产品出口额为被解释变量,进行回归分析。建立反映科研投入与高科技产品出口关系的模型,进行相关检验与修正,优化原有模型;最后,根据分析结果提出促进高科技产品出口的相关建议。
The export of high-tech products is conducive to optimizing China’s foreign trade structure and achieving the goal of becoming a strong trading nation.Investment in scientific research is an important factor in promoting scientific and technological innovation and the export of high-technology products.Using principal component analysis,the nine indicators reflecting scientific research investment are condensed into a comprehensive indicator.Then we take scientific research investment as the explanatory variables,high-tech product exports as the explained variables,conduct regression analysis,and establish a reflection of the relationship between scientific research investment and high-tech product exports model.Then we carry out relevant statistical tests and corrections to establish a more reliable regression model.Based on the results of the analysis,relevant suggestions to promote the export of high-technology products are made.
