Telecommunications, productivity and regional dependence: a comparative analysis between the Brazil, China and main developed regions in the post-reform period

Abstract In the last two decades, new technologies and rapid growth of telecommunications sector have changed production trade relations in world economic systems. Regional dependence on level productivity, supply demand has increased worldwide. Our study analyzes changes total factor productivity (TFP) verifies its global regional importance between 2000 2014. We apply TFP decomposition extraction technique an input−output model. The main findings suggest improved efficiency resulted gains developed countries, whose variations were lower than those Brazilian telecommunications, which exhibit a low capital—labor ratio. Moreover, is more sensitive to for telecommunications. Although effects output are intraregional, backward forward denote heavy reliance USA reciprocity China European countries. increase influenced by national policies countries with little emphasis composition should generate minor marginal TFP, even gain productive efficiency. These also expected reduce American Chinese
