یک مطالعه پویا از توسعه اقتصادی و رابطه مصرف رشد الکترونیکی

This study examines the relationship between electricity consumption and economic growth for 88 countries categorized into four panels based on the World Bank income classification (high, upper middle, lower middle, and low income) within a multivariate panel framework over the period 1990–2006. The Larsson et al. (2001) panel cointegration test indicates there is a long-run equilibrium relationship between real GDP, coal consumption, real gross fixed capital formation, and the labor force for the high, upper middle, and lower middle income country panels. The results from the panel vector error correction models reveal (1) bidirectional causality between electricity consumption and economic growth in both the short- and long-run for the high income and upper-middle income country panels; (2) unidirectional causality from electricity consumption to economic growth in the short-run, but bidirectional causality in the long-run for the lower-middle income country panel; and (3) unidirectional causality from electricity consumption to economic growth for the low income country panel.

Electricity serves an important role in both the production and consumption of goods and services within an economy. The availability of electricity has been a major contributor to the technological and scientific advancements that have improved the standard of living across countries. With population growth, urbanization, and industrialization of economies, the infrastructure for electricity has emerged as an important factor in a country's growth prospects. Furthermore, the growth of the information and communication technologies in advanced economies confirms the importance of electricity. In a study of over 100 countries, Ferguson et al. (2000) present evidence of a high correlation between electricity usage and the level of economic development and growth. However, a high correlation does not necessarily imply a causal relationship. Thus, understanding the causal relationship between electricity consumption and economic growth is important in the design and effectiveness of energy and environmental policies.

Electricity is a vital factor in the growth prospects of countries by facilitating scientific and technological advancements alongside the emergence of the information and communication technologies that have enhanced production and trade across countries. This study explores the causal relationship between electricity consumption and economic growth associated with four country panels based on income classification to discern if any differences based on the level of economic development. Specifically, the study examines the causal relationship between electricity consumption and economic growth including measures of capital and labor within a multivariate panel error correction model framework for 88 countries categorized into four income country panels (high, upper-middle, lower-middle, and low income) over the period 1990 to 2006.
