BACKGROUND
Life expectancy is a significant result indicator of public health and sustainable development. Therefore, one of the final objectives of all economic and social policies is to increase the life expectancy. In this context, a limited number of researchers have investigated the relationship between ICT penetration and life expectancy. However, multiple interaction channels exist between ICT penetration and life expectancy. Furthermore, the studies have usually focused on the effect of ICT penetration on life expectancy through regression and ignored the effect of life expectancy on ICT penetration to a large extent. Therefore, this study aims to contribute to the empirical literature by investigating the causal relationship between ICT indicators and life expectancy.
METHODS
This study uses symmetric and asymmetric causality approaches to investigate the two-way interaction between ICT indicators and life expectancy in emerging market economies over the 1997-2020 period. Employment of the asymmetric causality test enables us to analyze the hidden relationships between ICT indicators and life expectancy, unlike the traditional causality test.
RESULTS
The results of the symmetric causality test uncover a bidirectional causal interaction between mobile subscriptions and life expectancy but a one-way causal relationship from life expectancy to internet usage. However, the asymmetric causality test results uncover a unidirectional causal relationship between mobile subscriptions and life expectancy in China, Colombia, Czechia, Egypt, Greece, India, Kuwait and Turkiye due to positive shocks from mobile subscriptions. On the other hand, a bidirectional causal interaction exists between internet usage and life expectancy in all countries due to negative shocks from internet usage and life expectancy. Last, a unidirectional causal relationship exists between internet usage and life expectancy in all countries due to positive shocks from internet usage.
CONCLUSION
ICT indicators significantly influence life expectancy health in a sample of emerging market economies. Therefore, internet usage and mobile devices are significant tools to improve life expectancy.
背景
预期寿命是公共卫生和可持续发展的重要结果指标。因此，所有经济和社会政策的最终目标之一都是提高预期寿命。在这种情况下，为数有限的研究人员调查了信息通信技术普及与预期寿命之间的关系。然而，信息通信技术普及与预期寿命之间存在多种相互作用的渠道。此外，这些研究通常侧重于通过回归来研究信息通信技术普及对预期寿命的影响，而在很大程度上忽略了预期寿命对信息通信技术普及的影响。因此，本研究旨在通过调查信息通信技术指标与预期寿命之间的因果关系，为实证文献做出贡献。
方法
本研究使用对称和非对称因果关系方法，在 1997-2020 年期间调查新兴市场经济体中信息通信技术指标与预期寿命之间的双向相互作用。与传统的因果关系检验相比，非对称因果关系检验的运用使我们能够分析信息通信技术指标与预期寿命之间的隐藏关系。
结果
对称因果关系检验的结果揭示了移动订阅量与预期寿命之间存在双向因果相互作用，但预期寿命与互联网使用之间存在单向因果关系。然而，非对称因果关系检验的结果揭示了在中国、哥伦比亚、捷克、埃及、希腊、印度、科威特和土耳其，由于移动订阅量的正冲击，移动订阅量与预期寿命之间存在单向因果关系。另一方面，由于互联网使用和预期寿命的负冲击，所有国家的互联网使用和预期寿命之间存在双向因果关系。最后，由于互联网使用的正冲击，所有国家的互联网使用和预期寿命之间存在单向因果关系。
结论
信息通信技术指标对新兴市场经济体样本中的预期寿命健康有显著影响。因此，互联网使用和移动设备是提高预期寿命的重要工具。
