Energy plays an important role in economic development. This paper deals with the long-run relationship between energy consumption and real GDP for V4 countries from 2005 to 2019. The analysis was based on the unit root tests, co-integration tests, and causality tests. There are two questions. The first question is if energy consumption the stimulus to GDP, resp. energy consumption causes GDP. And the second question is if GDP the stimulus for energy consumption, resp. GDP causes consumption of energy. Energy consumption has an essential role in the economy on both the demand and the supply. It means that there should be a causal relationship from energy consumption to GDP as well as vice versa. Given that in the long run the energy consumption Granger causes the GDP in Slovakia, Hungary, and the Czech Republic, it means that energy consumption could cause economic growth in these countries. The only country where no significant relationship between energy consumption and the GDP has been demonstrated in Poland.

V4国家能源消费与经济增长的因果关系

能源在经济发展中发挥着重要作用。本文探讨了 V4 国家 2005 年至 2019 年能源消耗与实际 GDP 之间的长期关系。分析基于单位根检验、协整检验和因果关系检验。有两个问题。第一个问题是能源消费是否对 GDP 有刺激作用。能源消耗导致GDP。第二个问题是，如果 GDP 刺激能源消费，分别。GDP导致能源消耗。能源消耗对经济的需求和供应都具有重要作用。这意味着能源消耗与GDP之间应该存在因果关系，反之亦然。鉴于从长远来看，能源消耗格兰杰导致了斯洛伐克、匈牙利和捷克共和国的 GDP，这意味着能源消耗可能导致这些国家的经济增长。波兰是唯一一个能源消耗与 GDP 之间没有显着关系的国家。
