摘要：There have been some studies about the effect of development and research costs, human and physical resources on Iran per capita gross domestic product using linear equation during some recent decades. This study is sought to investigate the short-term effect of each one of mentioned investments on per capita gross domestic product using light transmission error correction model and for this, annual data for the period (1974-2015) have been used. The results show that non-linear model has higher explanatory power than linear one in a way that about human resources in the low threshold, they have the most effect on gross domestic product but in high threshold this effect has become negative. About physical capital and investment on development research costs in low threshold to average one, they have the most effect on economic growth but in high threshold this effect has reduced
