The Role of Training in the Productivity of Adult Human Capital in the Road Freight Transport

human labor is considered as the most important capital of any country, for this purpose the effective and optimal use or in other words effective productivity of this capital is one of the main goals and plans of countries at the macro level. Considering the importance of this issue and since human capital as one of the most important types of capital can play a significant role in the economic growth and development of the road transport sector, in this study the role of adult human labor in the productivity of the country's road transport sector has been examined. For this purpose, by collecting annual data and using the autoregressive Distributed Lag model and error correction model with the help of EVIEWS10 software, the model was estimated and the results were interpreted. The results show that both in the short term and in the long term, the working experience of people over 50 years old in the road freight transport sector, as well as the training of people over 50 years old in the road freight transport sector, in the productivity of the road freight transport sector. It has a positive effect. Finally, according to the error correction coefficient in the ECM model, it can be stated that the speed of adjustment towards the equilibrium and long-term value was appropriate. So that in each period about 0.227 the imbalance error is adjusted and the short-term value tends towards its equilibrium and long-term value exponentially.
