Trade Policy Uncertainty, Innovation and Total Factor Productivity

This paper explores the impact of trade policy uncertainty (TPU) shock on China’s total factor productivity. Using economic panel data for China, OECD countries, Hong Kong SAR, Macao SAR, and Singapore from the period 2003–2019, in this paper, we treat U.S.–China trade frictional events in 2016 and 2017 as a quasi-experiment to study the impact of TPU surge on China’s TFP under the synthetic control method (SCM) and generalized synthetic control method (GSCM), treating the OECD countries, Hong Kong SAR, Macao SAR, and Singapore as a control group. We found that TPU surge has a significantly negative causal effect on China’s TFP. SCM analysis, taking 2016 (2017) as the policy implementation time, showed that the average TFP loss borne by China due to trade policy uncertainty in 2017 and 2018 was 2.7% (3.5%). The VAR model showed that China’s trade policy uncertainty reduces China’s TFP through two channels: the shrinking channel of domestic R&D innovation, and the shrinking channel of the domestic sector’s use of foreign patents. This conclusion is robust according to the GSCM. To the best of the authors’ knowledge, this paper is the first attempt to examine the long-term technological impact of TPU surge during U.S.–China trade frictional events. Our findings suggest that trade friction harms technological progress, and reducing TPU can significantly enhance innovation and TFP.

Temporal and gene reassortment analysis of influenza C outbreaks in Hong Kong SAR, China

From 2014 to week 07/2020 the Centre for Health Protection in Hong Kong conducted screening for influenza C virus (ICV). A retrospective analysis of ICV detections to week 26/2019 revealed persistent low-level circulation with outbreaks occurring biennially in the winters of 2015-16 and 2017-18 (1). Here we report on an outbreak occurring in 2019-20, reinforcing the observation of biennial seasonality in Hong Kong. All three outbreaks occurred in similar time-frames, were subsequently dwarfed by seasonal epidemics of influenza types A and B, and were caused by similar proportions of C/Kanagawa/1/76 (K-)lineage and C/São Paulo/378/82 S1- and S2-sublineage viruses. Ongoing genetic drift was observed in all genes, with some evidence of amino acid substitution in the HEF glycoprotein possibly associated with antigenic drift. A total of 61 ICV genomes covering the three outbreaks were analysed for reassortment and nine different reassortant constellations were identified, one K-lineage, four S1-sublineage and four S2-sublineage, with six of these being identified first in the 2019-20 outbreak (two S2-lineage and four S1-lineage). The roles that virus interference/enhancement, ICV persistent infection, genome evolution and reassortment might play in the observed seasonality of ICV in Hong Kong are discussed. Importance Influenza C virus (ICV) infection of humans is common with the great majority of people being infected during childhood, though re-infection can occur throughout life. While infection normally results in ‘cold-like’ symptoms, severe disease cases have been reported in recent years. However, knowledge of ICV is limited due to poor systematic surveillance and an inability to propagate the virus in large amounts in the laboratory. Following recent systematic surveillance in Hong Kong SAR, China and direct ICV gene sequencing from clinical specimens a two-year cycle of disease outbreaks (epidemics) has been identified with gene mixing playing a significant role in ICV evolution. Studies like those reported here are key to developing an understanding of the impact of influenza C virus infection in humans, notably where comorbidities exist and severe respiratory disease can develop.

The Radicalization of Young Protesters in Hong Kong: Under the Context of Globalization and Power Relations

This paper takes the social unrest in 2019 as a case study and identifies three factors that contributed to the radicalization of social protests in Hong Kong: globalization, digitalization and the U.S. meddling in Hong Kong affairs. First, with the deepening of globalization, the worsening of social-economic conditions had bred populism among the youth. Second, digital technologies and social media platforms also made it easy for young people in Hong Kong to protest in a more covert and radical way. Third, the U.S. support for the Hong Kong opposition leaders added fuel to the radicalization of youth protesters. All these factors finally led to radicalized social protests in Hong Kong. Nevertheless, following the implementation of the National Security Law in Hong Kong SAR, violent activities were largely stopped and social order was gradually restored.

Detection of Ophidiomyces ophidiicola in a wild Burmese python (Python bivittatus) in Hong Kong SAR, China.

Ophidiomycosis (also referred to as snake fungal disease) is an emerging infectious disease caused by Ophidiomyces ophidiicola ( Oo ). PCR was used to detect Oo in a Burmese python ( Python bivittatus ) submitted to a rescue center in Hong Kong with skin lesions. This is the first documented case of ophidiomycosis in Asia and the first detection of this disease in this species. More research is needed in Asia to determine the prevalence of this mycosis, its relationship with other species and its ecological importance. These findings also highlight a significant role played by wildlife rescue centres in monitoring wildlife diseases and ecosystem health
