Abstract ：
为探讨中国渔业国际竞争力状况及其背后的影响因素，首先，从市场份额、净出口和比较优势3个角度，运用国际市场占有率、贸易竞争力指数和显示性比较优势指数，对中国和世界主要渔业生产国（地区）的渔业国际竞争力进行测定与比较；其次，以波特的“国家钻石”模型为依托，结合渔业的实际情况，构建渔业国际竞争力的理论分析框架，并对不同角度测量的中国渔业国际竞争力的影响因素进行实证分析；最后，提出提升中国渔业国际竞争力的政策思考。结果表明：1）市场份额层面，中国渔业国际竞争力在世界主要出口市场中最强；2）净出口层面，中国的TC指数不断下降，竞争优势在不断丧失；3）比较优势层面，在主要水产品出口国中，中国比较优势不明显，且正逐步丧失；4）初级生产要素是推动中国渔业国际竞争力提升的关键，高级生产要素对渔业国际竞争力的促进作用较小，人力资本成为制约中国渔业国际竞争力提升的重要因素；5）内部需求条件、相关与支持性产业和渔业发展战略均促进了中国渔业的国际市场占有率和比较优势的提升，但阻碍了净出口反映的国际竞争力的提升。

Abstract ：
Saccharina japonica is a cold-water macroalga mainly distributed in the coastal areas of the North Pacific Ocean and the Atlantic Ocean, and it is one of the seaweed varieties with the largest culture production in the world. S. japonica cultivation plays a pivotal role in the aquaculture industry of China's coastal provinces. In recent decades, China's S. japonica production has steadily increased, and the country has become the largest producer and exporter of S. japonica in the world. This paper presents in detail the development status of China's S. japonica industry from the aspects of S. japonica varieties, main production areas, culture production and area, seedings, processing, brands, import and export trade, culture models and disease. The paper further discusses the challenges faced in the development of China's S. japonica industry and proposes a series of strategic solutions to foster its sustainable growth. These efforts aim to provide Chinese experiences and viable strategies for other S. japonica farming countries in the world.

Abstract ：
Introduction Green Total Factor Productivity (GTFP) serves as a key indicator for assessing an industry's green development performance.Methods Based on panel data from nine coastal provinces in China from 2013 to 2023, this study constructs an evaluation indicator system for the Green Total Factor Productivity of China's mariculture industry, conducts measurements, analyzes its temporal evolution characteristics, reveals its regional disparities, and assesses its dynamic evolutionary trends.Results (1) From 2013 to 2023, the average GTFP of China's coastal mariculture industry was 0.93, indicating room for further improvement in the level of green development. After 2020, the GTFP began to show a sustained increase, suggesting initial signs of effectiveness in the green transition of the mariculture sector. The growth of GTFP was jointly driven by both green technical change and green technical efficiency change; however, the contribution of technical change exceeded that of efficiency change gains. (2) There are significant provincial disparities in the GTFP of the mariculture industry. The average GTFP values of Liaoning, Hainan, Guangxi, Guangdong, and Shandong exceeded 1. The averages for Fujian, Zhejiang, and Jiangsu ranged between 0.8 and 1.0, while Hebei recorded the lowest average of 0.6. Inter-regional differences were identified as the primary source of the overall disparity. (3) In the short term, provinces with low GTFP levels face challenges in overcoming their backward status, while provinces with high levels can easily maintain their leading positions, indicating a phenomenon of polarization. In the long run, the probability of provinces with low and medium GTFP levels transitioning to higher levels increases significantly. The likelihood of a province moving upward is positively correlated with the GTFP levels of its neighboring provinces. The driving effect from adjacent medium-level provinces is the strongest. Proximity to high-level provinces may produce a "double-edged sword" effect.Discussion Based on these findings, this paper proposes recommendations to increase investment in core technology research and development, promote regional coordinated development, and implement differentiated performance evaluations.

Abstract ：
Abalone is a single-shell mollusk existing in the Pacific, Atlantic, and Indian Oceans. China has abundant abalone resources and a long history of abalone consumption. Abalone aquaculture is an important economic and social activity in China’s coastal provinces. The country’s abalone production has increased significantly in recent decades, and it is now the largest producer and consumer of abalone in the world. However, there is minimal literature depicting the entire abalone industry of China. This research outlines the current status of the abalone industry in China, including overall domestic production trends, producing areas, main farming species, bait and feed products, aquaculture models, market prices and consumption, processing, and import and export trade. Furthermore, this study identifies challenges in the development of China’s abalone industry and proposes a series of solutions to ensure the sustainability of the abalone industry. It provides a basic reference for future studies and policy‐making in the field of the abalone sector. Although the current study focuses on China, the challenges and solutions discussed have considerably broad implications for the global abalone industry. © 2024, The Authors. All rights reserved.

Abstract ：
Introduction: The employment psychology and issues being faced by university students have garnered significant attention after the COVID-19 outbreak. Methods: Focusing on Chinese university students, this study compares the changes in their employment psychology between the initial and normalization stages of COVID-19 prevention and control in China and examines their employment choices during the normalization stage. This study also investigates how the transformed employment psychology of these students influences their employment intentions. Results: (1) Chinese university students exhibit stronger feelings of employment confusion, anxiety, stability preference, uneasiness, and inferiority during the normalization stage compared with the initial stage, thus leading to a more negative employment psychology; (2) during the normalization stage, university students display a more pessimistic outlook on their employment situation and show their preference for direct employment, particularly in public institutions, state-owned enterprises, and government organizations. They also show a greater interest in working in first-tier cities than in their hometowns; (3) the employment psychology of these students in the post-pandemic period significantly influences their employment intentions, with employment stability preference psychology playing a crucial role; and (4) the employment stability preference psychology positively and significantly affects the employment intentions of junior college students. Conversely, this employment stability preference psychology has a negative effect on the employment intentions of academic master's and doctoral students. This paper also proposes some strategies to enhance the employment psychology of university students and improve their quality of employment at various levels, including government, school, enterprise, family, and individual.

Abstract ：
The psychological problems and employment problems of college students have always been the focus of attention of all sectors of society. The COVID-19 epidemic has a great impact on the mental health and employment of Chinese college students. Under this background, this study discusses how epidemic anxiety affects the employment confidence and perception of employment situation of Chinese college students. Through the online questionnaire survey of 1,132 college students nationwide, and the ordinal logistic regression analysis of the survey data using Stata 16.0 software, the results show that: (1) Epidemic anxiety negatively affects Chinese college students' employment confidence and employment situation perception, and has a significant impact on employment confidence. The three control variables of employment guidance, older age and higher education have a significant positive impact on college students' employment confidence and employment situation perception. College students in the eastern region have stronger employment confidence and more optimistic employment situation perception. But the expected monthly salary is negatively correlated with employment confidence. (2) Male college students and Science and Engineering students' epidemic anxiety have a stronger negative impact on employment confidence and employment situation perception. (3) Employment guidance has a moderating effect on the relationship between epidemic anxiety, employment confidence and employment situation perception. Employment guidance can enhance college students' employment confidence and reduce their sense of employment crisis by alleviating epidemic anxiety. Combined with the research conclusions, it is proposed that the state and schools should pay attention to the psychological counseling of college students, strengthen the employment guidance of colleges and universities, vigorously support the development of small, medium-sized and micro enterprises, and improve the employment and entrepreneurship service system of college students, so as to promote the employment of college students.

Abstract ：
China is a massive country with a large number of fishermen. With the continuous improvement of fishing technology, a timely transfer of surplus fishing labor is important in protecting natural fishery resources. Using data from the China Fishery Statistical Yearbook, the National Bureau of Statistics of China, the regional economic database of China, and the statistical yearbooks of various provinces and cities, this study performs a Granger causality test to analyze the job transfer pathway of fishermen, combines labor transfer theory with the characteristics of marine fishing production to build a theoretical framework for analyzing those factors that drive the conversion of marine fishermen, and uses a panel data model for an empirical analysis. Results show that (1) non-marine fisheries and part-time industries are the main pathways for the conversion of marine fishermen; (2) the technological progress of capture fisheries is an important driver of the conversion of marine fishermen; (3) the continued urbanization, increase in the number of part-time jobs, and the income gap between marine fishermen and rural residents are important factors that hinder such conversion; (4) the investment in fixed assets per capita of fishermen and their per capita income do not significantly affect the conversion of fishermen; and (5) the significant effect of the income gap between marine fishermen and urban residents on the conversion behavior of the former is not supported by any evidence. This article also suggests some countermeasures for promoting the conversion of fishermen.
