Cross-border Investment and Economic Integration: The Case of Guangdong Province and Hong Kong SAR
Full text linkIn this paper, we undertake a comparative study of the performance of local and foreign competitors’ manufacturing firms in a FDI-recipient region—Guangdong Province, China—and analyzes the policy implications of the comparison for the advanced, FDI-outflow region—Hong Kong Special Administrative Region (HKSAR). By highlighting changes in productivity that vary with changes in manufacturing firm ownership, we reveal that domestic firms have been catching up with their foreign counterparts, including Hong Kong-based firms, though foreign firms have successfully strengthened their dominating position in Guangdong’s manufacturing industry.Total Factor Productivity, Manufacturing Sectors, Asia, China, Guangdong, Hong Kong
Standard operating procedure and quality control standards for intravitreal injection in Guangdong Province
No full textIntravitreal injection represents the primary method of drug administration for a range of common chronic endophthalmic diseases, including age-related macular degeneration, diabetic retinopathy and retinal vein occlusion.Recognized for its high clinical efficacy, procedural standardization, and operational accessibility, this has become a routine clinical practice in ophthalmology. In alignment with the "National Eye Health Plan during the 14th Five-Year Plan period (2021–2025)" and the patient-centered service philosophy, this approach optimizes treatment processes and enhances patient experience and therapeutic outcomes while ensuring medical safety. Furthermore, Guangdong Province is poised to become a pivotal hub for ophthalmic care within the Guangdong-Hong Kong-Macao Greater Bay Area, anticipating a growing influx of patients from Hong Kong and Macao. This necessitates the development of a unified intravitreal injection standard tailored to regional healthcare integration. Under the auspices of the Guangdong Medical Association, a consortium led by Zhongshan Ophthalmic Center, Sun Yat-sen University, and 21 collaborating medical institutions across Guangdong, formulated this standard. Through iterative reviews involving correspondence-based evaluations and multidisciplinary expert consultations, 35 distinguished specialists refined the standard,synthesizing global best practices with insights into the Greater Bay Area’s unique ophthalmological landscape. This group standard systematically outlines the basic requirements, indications and contraindications of intravitreal injection,establishes a new standard operating procedure for intravitreal injection and quality control standards for this procedure.In addition, we have introduced guidance for the clinical application of this technique and quality assessment, as well as for the prevention and management of complications or adverse reactions

Standard operating procedure and quality control standards for age-related cataract in Guangdong Province
No full textAge-related cataract is the leading blinding eye disease in the world, and surgery is the only effective treatment. The good recovery of vision after cataract surgery depends not only on the patients’ ocular conditions but also on the surgical technique and quality management level of medical institutions. Standard surgical procedures, the accurate measurement and calculation of intraocular lens (IOL) power, and professional perioperative management are the keys to restoring the sight of patients. In addition, the National Health Commission proposed in the "Work Plan for Strengthening the Cataract Surgery Capacity Building of County-level Hospitals (2025-2027)" that the ability of county-level hospitals to perform cataract surgery should be further improved by strengthening the construction of equipment and facilities, assisting county-level hospitals in carrying out personnel training, and establishing standardized surgical system. Therefore, in order to standardize cataract surgery procedures, ensure the safety of the surgery and reduce surgical complications, under the leadership of the Guangdong Medical Association, the Zhongshan Ophthalmic Center of Sun Yat-sen University, in conjunction with 21 other medical institutions in Guangdong Province and 35 authoritative experts, jointly drafted this group standard. On the basis of referring to the domestic and international standards for cataract surgery and combining with the current situation of cataract surgery in Guangdong Province, they jointly determined this group standard. This group standard systematically describes the basic requirements for the software and hardware conditions of age-related cataract surgery, the indications and contraindications of the surgery, formulates the standard surgical procedures and quality control standards for cataract surgery, and introduces the prevention and treatment of complications or adverse reactions, providing guidance for all qualified medical institutions at different levels to carry out cataract surgery and quality assessment
Syphilis test availability and uptake at medical facilities in southern China.
Full text linkOBJECTIVE: To examine syphilis testing capacity, screening coverage rates and types of syphilis tests used in medical facilities in southern China. METHODS: Eleven of the 14 municipalities in Guangdong province participated. Data on syphilis testing capacity, screening coverage and types of syphilis tests used were collected from all types of public medical facilities offering prenatal care (n = 109). A total of 494 680 women who delivered during 2004-2008 were studied. FINDINGS: In 2008, 54 196 pregnant women (43.1%) were not screened for syphilis. Among such women, 32 863 (60.6%) attended clinics without any syphilis testing capacity and 21 333 (39.4%) attended clinics that performed testing but were not screened. The likelihood of not having syphilis test capacity was much higher for hygiene stations (odds ratio, OR: 10; 95% confidence interval, CI: 4-25), services at the township level (OR: 33; 95% CI: 10-100) and services with ≤ 1000 deliveries per year (OR: 1.002; 95% CI: 1.001-1.003). These same service characteristics correlated with lower screening coverage rates (P < 0.01). Only one antenatal clinic had the capacity to conduct both treponemal and non-treponemal tests for diagnosing syphilis. CONCLUSION: Syphilis screening is available in very few of the basic medical facilities offering prenatal care where most neonates in southern China are delivered. In light of this and of the increasing incidence of syphilis in the area, expanding point-of-care rapid syphilis testing is a priority
Genomic epidemiology of SARS-CoV-2 in Guangdong Province, China
Full text linkCoronavirus disease 2019 (COVID-19) is caused by SARS-CoV-2 infection and was first reported in central China in December 2019. Extensive molecular surveillance in Guangdong, China’s most populous province, during early 2020 resulted in 1,388 reported RNA-positive cases from 1.6 million tests. In order to understand the molecular epidemiology and genetic diversity of SARS-CoV-2 in China, we generated 53 genomes from infected individuals in Guangdong using a combination of metagenomic sequencing and tiling amplicon approaches. Combined epidemiological and phylogenetic analyses indicate multiple independent introductions to Guangdong, although phylogenetic clustering is uncertain because of low virus genetic variation early in the pandemic. Our results illustrate how the timing, size, and duration of putative local transmission chains were constrained by national travel restrictions and by the province’s large-scale intensive surveillance and intervention measures. Despite these successes, COVID-19 surveillance in Guangdong is still required, because the number of cases imported from other countries has increased
Managing the interface between public sector applied research and technological development in the Chinese enterprise sector
Full text linkChina's technological capabilities are emerging rapidly and the country will become a major challenger to established nations in terms of R&D and innovation in the near future. For the moment, however, contradictory signals emerge from the Chinese economy leaving experts pondering about the country's true potential for technological upgrading on a broad scale. The integration of the domestic research system, international technology transfer, and technological development remains limited to a few high-tech companies, while large segments of the domestic private sector have limited access to knowledge and technologies to upgrade their activities. --China,Guangdong,interface,knowledge supply,knowledge demand,regional innovation system,science-industry relations
