Abstract
Proceeding from the important role played by capital accumulation, as it is the main solution to most of the complex challenges of developing countries, the research sought to provide a theoretical framework on external sources of capital formation, as well as finding the relationship between some financial and economic variables (domestic credit provided to the private sector, trade, And total exports of goods and services, total imports of goods and services, exchange rate, real interest rate, foreign direct investment (net inflows), total savings, inflation, and the total value of traded shares) and capital accumulation for Jordan, using time series data for the period (1990-2020), based on the so-called Autoregressive Distributed Time Lapse (ARDL) methodology. The research reached several conclusions, the most prominent of which was that savings had a positive effect in the long run in Jordan, which reflects that higher savings lead to higher investments and then increased capital accumulation. Through awareness campaigns to encourage saving.
