摘要
本研究旨在研究2005-2019年发展中国家面板中信息通信技术(ICT)扩散、金融发展和经济增长之间的关系。设计/方法/方法本研究采用主成分分析(PCA)提取ICT扩散指标。采用Levine Lin Chu (LLC)、Im Pesaran Shin (IPS)、Augmented Dickey-Fuller (ADF)和Phillips and Perron (PP)等第一代面板单位根检验检验变量的平稳性。采用Pedroni和Kao协整技术检验长期关系的存在性,并采用FMOLS和动态普通最小二乘(DOLS)估计协整系数。面板格兰杰因果关系法检验了短期和长期因果关系。研究结果证实,信息通信技术扩散、金融发展和贸易开放促进了经济增长,而通货膨胀抑制了经济增长。此外,因果关系检验表明,在发展中国家,ICT增长与金融发展增长之间存在双向因果关系,但金融发展与ICT扩散之间存在单向因果关系。独创性/价值该研究建议同步公共和私营部门投资,以对ICT基础设施产生协同效应,并在金融部门进行充分投资,以提高发展中国家的增长率。应采取经济政策鼓励和补贴,以确保弱势社区能够负担得起信息通信技术服务。此外,建议开展以提高数字素养为重点的培训项目,使各阶层人口都能使用数字平台进行金融服务。
Impact of ICT diffusion and financial development on economic growth in developing countries
PurposeThe present study aimed to examine the relationship between information and communication technologies (ICT) diffusion, financial development and economic growth in the panel of developing countries for 2005–2019.Design/methodology/approachThe study employed the principal component analysis (PCA) to extract the index of ICT diffusion. First-generation panel unit root tests such as Levine Lin Chu (LLC), Im Pesaran Shin (IPS), Augmented Dickey-Fuller (ADF) and Phillips and Perron (PP) were employed to check the stationarity of the variables. Pedroni and Kao co-integration techniques were used to examine the existence of the long-run relationship, and co-integration coefficients were estimated using FMOLS and dynamic ordinary least squares (DOLS). The panel Granger causality approach examined the short-run and long-run causality.FindingsThe results confirmed that ICT diffusion, financial development and trade openness accelerate growth, whereas inflation dampens economic growth. Further, the causality test showed bidirectional causality between ICT growth and financial development growth but a unidirectional causality from financial development to ICT diffusion in developing countries.Originality/valueThe study recommends synchronizing public and private sector investment for a synergistic effect on ICT infrastructure and adequate investment in the financial sector to increase the growth rate in developing countries. Economic policies should be adopted toward incentives and subsidies to ensure affordable ICT services for disadvantaged communities. Also, training programs focussing on enhancing digital literacy to enable all segments of the population to use digital platforms for financial services are recommended.
