Reciprocal Tariffs and Systemic Trade Losses
The resurgence of U.S. protectionism, the proposal of universal reciprocal tariffs targeting major trading partners, poses systemic risks to global trade that existing bilateral analyses have not fully captured. This paper examines the economic consequences of U.S. reciprocal tariff imposed simultaneously on imports from Korea, Japan and the European Union (EU). Using highly disaggregated HS‐10 bilateral trade data from the USITC (2024), we estim…
Tourism as a Trade Facilitator
This study examines how international tourism affects Vietnamʼs bilateral trade flows with major partners, framing the analysis within a structural gravity model of trade. Using system‐GMM estimation on panel data from 20 countries (2008–2022), the analysis disaggregates trade flows by direction (exports vs. imports) and by category (goods vs. services, with tourism‐related service trade excluded to avoid tautology) to capture tourismʼs varied ef…
Industrial Transformation and Environmental Sustainability
The synergistic management of carbon emissions and PM2.5 pollution (SCPM) represents a critical challenge for China’s 6G. This study examines the impact of China’s “Made in China 2025” (MIC) industrial policy on SCPM using a time-varying difference-in-differences approach with panel data from 284 Chinese cities (2003–2021). We construct SCPM as an interaction term between carbon emissions and PM2.5 concentrations to capture their synergistic envi…
Impact of Free Trade Zones on Chinaʼs ICT Products Trade
It investigates the impact of Chinaʼs FTZs on the countryʼs trade in ICT products—a sector central to Chinaʼs industrial digitisation and integration into global value chains—by applying a propensity score matching difference‐in‐differences (PSM‐DID) approach to bilateral trade data between China and 35 partner countries from 2000 to 2022. The analysis finds that the expansion of Chinaʼs FTZ network, which by the end of 2023 encompassed 22 agreem…
Tourism Development, Foreign Direct Investment, and Environmental Sustainability
Tourism drives economic growth and impacts the environment. This study examines the nonlinear relationships among tourism development, economic growth, foreign direct investment, economic globalization, renewable energy consumption, and greenhouse gas (GHG) emissions in the Organization for Economic Co-operation and Development economies from 1995 to 2020. It also explores how green technological innovation (GTI) moderates and influences the link…
The Dual Effects of Green Trade on Boosting Sustainability and Challenging Productivity
This study examines the impact of green trade (GT) on both environmental sustainability and economic productivity across 33 Organization for Economic Co-operation and Development countries. The findings reveal that while GT contributes to lower carbon emissions, its influence on productivity is mixed. In countries with moderate productivity levels, GT supports further growth. However, in more advanced economies, additional GT may slow productivit…
Security or sovereignty
This research delves into the examination of the impact of political crisis events between nations on Chinese outbound tourism. By utilizing the synthetic control method, the study examines the effects of three significant disputes – the THAAD, Diaoyu, and Huangyan dispute – on the number of Chinese tourists visiting countries that are involved in the disputes. The paper compares the impact of various types of political events and finds that disp…
The effect of trade on the gender gap in labour markets
This study analyses the impact of international trade on the gender gap in labour force participation while considering the moderating role of information and communication technologies (ICT). Our analyses of panel data from 79 developing economies over 2006–2019 reveal that international trade narrows gender gap, and the interaction between trade and ICT is likely to widen it. Further, the impact of these two parameters on the gender gap varies …
Toward sustainable development
The direct and moderating impact of digitalization on the gender gap in the labor force participation rate is explored in this study. By analyzing the panel data of the G20 countries for the period of 2006–2021, we find that (1) the rising level of digitalization tends to narrow the gender gap in the labor force participation rate, with a greater gender gap‐narrowing effect in high‐income countries than in upper‐middle and lower‐middle income cou…
Has the Internet increased FDI, economic growth, and trade? Evidence from Asian economies
This study examines the causal relationship between the Internet and economic factors in Asian economies between 1997 and 2017. The economic factors consist of gross domestic product (GDP), foreign direct investment (FDI), imports, and exports. A comparative analysis of East, South, and Western Asia was conducted using a panel vector autoregressive model. The findings show bidirectional causality between FDI and Internet use in South Asia, unidir…
Does e-commerce narrow the urban–rural income gap? Evidence from Chinese provinces
Purpose A wide urban–rural income gap exists in China despite the implementation of pro-rural policies. Additionally, with the proliferation of the internet and information technology, the promotion effect of e-commerce on the economy has become apparent. Accordingly, China has been actively encouraging rural households to participate in e-commerce activities. This study aims to examine the effect of e-commerce on the urban–rural income gap. Desi…
