The expansion of the concept of finance, other influential factors in addition to physical assets and labor force have been identified in the economic growth process. One of those factors is the productivity of resources influenced by a variety of other factors including knowledge. The purpose of the present article is to categorize and scrutinize a long-run relationship and convergence among a diversity of knowledge variations in the framework of the Knowledge-Based Economy (KBE) in Iran during 1993-2013. To do so, Tukey and PCA techniques were applied to categorize and derive components of KBE indicators. Moreover, ARDL bound test was used to determine a long-run relationship among the variables. Based on the test, the existence of the independent convergence vector between knowledge and economic growth was proven indicating that there is a long-run relationship among KBE components. After determining the order of VAR, based on AIC, vector error correction model was estimated and ECM coefficient of-0.6324 was obtained showing that the speed of deviation adjustment from short-run to long-run is slow.
