Nowadays, the marine economy has been an important development issue in the world because this economy provides an opportunity to achieve sustainable development, particularly by a country that has rich marine resources, such as China. In actual fact, marine economic growth has been a powerful engine of Chinese economic growth, and has given rise to considerable attention and discussion because of the very high speed of this growth in the last two decades. However, the resource is not infinite and the marine environment is fragile. The resource and environment could offer a limitation to marine economic growth. Marine environmental regulation would be a good way to protect the marine resource and the environment. Furthermore, marine environmental regulations could affect the technology of the relevant enterprises, and then improve the total factor productivity (TFP) of the marine industry. Appropriate marine environmental regulations can be the key to making blue (marine) economic growth green (sustainable development). In order to identify the appropriate marine environmental regulations and development policies, this paper analyzed the influence of marine environmental regulations on total factor productivity in the marine industry in China. First, this paper constructed two microeconomic models to investigate the influence of command-based and incentive-based marine environmental regulations on total factor productivity theoretically. The paper then analyzed the influence of regulations and other political factors on the TFP by using quantitative analysis. We used panel data consisting of 11 coastal provinces and cities in China, covering the period from 2006 to 2015. We classified the 11 coastal provinces and cities into four sub-groups, based on their location, as Bohai Sea, the Yangtze River Delta, the Pan-Pearl River Delta, and Beibu Gulf. We found that the influence of marine regulation on total factor productivity is dynamic (not simply positive or negative), and the results are spatial heterogeneities. In the areas around Bohai Sea, the Yangtze River Delta and the Pan-Pearl River Delta, the effect of marine environmental regulations is more significant, while the effect of marine environmental regulations on total factor productivity is lower in the Beibu Gulf. This paper also discussed the effects of other political factors (such as human capital, R&D, openness, and ownership) on TFP. To conclude, policy suggestions are provided for policymakers.

This study analyzed changes in the Yangtze River Delta Economic Zone Development Plan and foreign investment trends and derived some implications. After China entered the WTO in 2001, foreign investments rapidly increased in the Yangtze River Delta Economic Zone. But cities in the economic zone competitively sought to attract foreign capital and this led to an adverse effect of excessive competition. In particular, each area in the zone designated a vast industrial complex and the functions and roles of industrial complexes overlapped and this made foreign investors experience some confusion in selecting investment locations. Previous studies on the Yangtze River Delta Economic Zone mostly analyzed investment environments, investment and advance methods and investment outcome. In 2020, the Chinese government formulated the ‘outline of the integrated regional development of the Yangtze River Delta’ in a bid to solve the problem of competitive overlapping investment and development in the areas of the Yangtze River Delta and develop strong points of each area. Particular attention is paid to changes in the Yangtze River Delta Economic Zone Development Plan for setting a direction and strategies of foreign investment. Therefore, this study analyzed the foreign investment status in relation to the outline of the integrated regional development of the Yangtze River Delta to provide Korean companies with meaningful implications in reviewing the investment direction and methods to use the direction in the Yangtze River Delta Economic Zone. This study analyzed the types of industries of 3,772,297 foreign-funded companies, which have entered the Yangtze River Delta Economic Zone to make investments, using statistical data provided by China. This study analyzed the types of industries in which foreign investments are made and changes in decade cycles in major cities of Chinese provinces, such as Shanghai, Hangzhou, Nanjing and Hefei. The analysis found that in Shanghai, investments are decreasing in the primary and secondary industries while they are increasing in the tertiary industry. In Nanjing (Jiangsu Province), investments in the manufacturing industry continue to increase with some transition into the advanced technology industry. In Hangzhou (Zhejiang Province), investments are decreasing in the manufacturing industry, while they are rapidly increasing in the service industry. Lastly in Hefei (Anhui Province), investments are continuously made in the manufacturing industry.

Piracy is the most difficult and important problem in the 21st century. Regardless of whether it is for countries that advocate high-intensity copyright protection, or countries that implement minimum protection levels in accordance with international treaties, all copyright countries around the world have made great achievements in copyright in China since the reform and opening up. On the basis of digestion, absorption, and re-innovation, China quickly established a complete intellectual property legal system. According to the "Outline of the National Intellectual Property Strategy", China is committed to the rapid economic development of intellectual property creation, utilization, and universally facing the world The contradiction between China’s demand for intellectual property rights and the excessively high international intellectual property protection standards. How to establish a high-level intellectual property protection system while ensuring rapid economic growth? China has submitted a Chinese proposal to the world. Committed to assisting others who oppose the protection of entry deterrence and intellectual, and the boots establish a new level of intellectual property protection that is more in line with all national interests built into it.

This is a study of promoting China free trade under China-US economic trade friction. China and the United States are the two largest economies in the world, and the China-US economic and trade friction has had a profound impact on world economy and trade patterns. The worsening of this economic and trade friction has caused a new round of changes in the global economy and trade. With such a backdrop, China and the United States will certainly consolidate and expand other trading partners to hedge their own losses. Scholars have confirmed that this economic and trade friction has caused a decrease in the total volume of trade between China and the United States, and even the world at large, but the allied countries that have close trade relationships with China and the United States have gradually expanded the shares of their external trades. Simultaneously, against the backdrop of this China-US economic and trade friction, China has started adjusting the share of its international trading partners, gradually decreased its dependence on developed economies such as European countries and America, and boosted its trade diversification, thereby dispersing trading risk. Additionally, China is actively seeking industrial restructuring, has put forward the concept of ''new infrastructure'', and has increased governmental support for chips, new energy, and the digital economy, while it is determined to vigorously develop high-end manufacturing, intelligent manufacturing, biomedicine, and aerospace industries. On the other hand, South Korea has mature and advanced industrial systems and advanced technical research and development mechanisms. Therefore, both China and South Korea have their own relative advantages in trading. Although a China-South Korea free trade agreement (FTA) has been reached, the utilization rate of the FTA remains to be raised. Moreover, there are relatively few trades in the high-end industry between China and South Korea, and China-US economic and trade friction is both a challenge and an opportunity for China and South Korea, which are the most important trading partners for each other. In the present study, the rich practical experiences and achievements obtained based on FTA strategies in China and South Korea were reviewed, the problems in the FTA strategies in the two countries were proposed, and the probability that China-South Korea free trade can be deepened according to these problems was analyzed. This study aims to provide new ideas for the industrial adjustment and establishment of innovative systems that deepen China-South Korea free trade. Regional strategic cooperation promotes regional economic development. Thus, China and South Korea start from free trade, learn from the world's advanced FTAs, and continue to innovate, thereby jointly injecting a new impetus into the world economy.

Today, the Chinese coffee market occupies a crucial position in the world. It is believed that the Chinese coffee market has an outstanding potential in the future. Therefore, the current Chinese coffee market occupies a crucial position globally, and brand coffee shops from around the world are also dominating the Chinese market. That is why so many brand coffee shops across cultures and areas attempt to occupy the Chinese market. According to theoretical background review this study examines the effects of brand experience and brand personality of coffee shop brands on customer satisfaction and brand loyalty. We also explore whether marketing localization moderates the relationship between brand experiences and brand personality, on the one hand, and customer satisfaction, on the other hand. Also we explore the brand globality's moderate effect between customer satisfaction and brand loyalty. The data were collected via survey with businessmen who frequently visit global coffee shops or university students exposed to various cultures. A total of 300 copies of the questionnaire were distributed, and 284 copies were retrieved. Upon exclusion of incomplete data, 271 responses were used for further empirical analysis. The results of this study revealed that only behavioral experience among the four brand experiences significantly affects customer satisfaction. Moreover, sincerity and ruggedness were found to significantly affect customer satisfaction (p<0.05 and p<0.01, respectively). We also found a significant relationship between customer satisfaction and brand loyalty. Furthermore, in line with our hypothesis, marketing localization did not significantly moderate the relationship between brand experiences and brand personality, on the one hand, and customer satisfaction, on the other hand. The moderating effect of brand globality was not statistically significant. These results showed that brand experience and brand personality have a partial impact on satisfaction. Furthermore, based on the findings, theoretical implications such as the importance of localization and globality, and managerial implications such as management of coffee shop brand were presented, and finally we suggested future research directions.

Power-law distribution exists in the world around us. The foretime research on power law distribution has been well-developed and complete widely used in the areas of physics, sociology, biology and finance. The public art is the most extensive form of contact between the public and art such as likes and dislikes in contact. Power-law distribution is the basic attribute of public art. Power-law distribution of public art means that the academic level of public art works is inversely proportional to the power index of the number of audiences. That is to say, the number of audiences of public artworks are easy to access can be understood by many. On the contrary the exploratory public art can only be discussed and studied by the professionals and insiders. This research is based on the study of the index relationship between the academic nature of public artworks and the number of audiences. There are four divisions of power-law distribution in public art: experimental public art (dominated by individuality), commercial public art (Individuality is greater than generality), mainstream public art (Generality is greater than individuality) and daily aesthetic public art (dominated by generality). The number increases exponentially in turn, and plays a role in their respective niches, and forms competition and evolution, promoting the development of public art. Based on the power-law distribution phenomenon in the field of mathematics, this paper divides public art into four types. It expounds the respective value orientation and attributes into four types of public art from the perspectives of politics, economics and daily aesthetics. Its research significance lies in systematically making sense of the important roles played by different types of public art in social development using the logic of mathematical model. This research method is different from the past public art research in the perspective of traditional art history. It not only focuses on the public art itself but also brings the aesthetic object (audience group) of public art into the research category. It points out the relationships between them. This study of public art provides new possibilities.

Zhu Ziqing was a distinguished academic who paid great attention to library work and participated in library collection development during the Republican Era of China. While his work is primarily known for advancing the discipline of Chinese Literature, Zhu Ziqing also closely combined library collection development with the research and teaching activities within the Department of Chinese Literature at Tsinghua University. During a tenure of about 23 years at Tsinghua University, Zhu Ziqing reviewed and recommended nearly 2,900 works of literature. He also contributed to the collection development at the Tsinghua University Library as a participant, builder, and manager, among other roles. Through historical document and textual analysis, this research paper explores and describes the scholarly and administerial contributions of Zhu Ziqing to the Department of Chinese Literature and Tsinghua University Library as well as analyzes the collection development concepts and policies advanced by Zhu Ziqing and adopted by the Tsinghua University Library during the Republican Era of China.

With the rising complexity of the global economic environment and international relations, countries all over the world have been looking for new development ideas. The mode of regional economic development has become an indispensable strategy for the economic development of Korea and China. In this context, The China-South Korea Free Trade Agreement was reached, the provisions of which deal with a wide range of trade issues such as specific countries that are covered by the agreement, quantity, and scope, permitting the largest degree of freedom. Based on the establishment of the China-South Korea FTA, this paper explores the economic effect of the Korea-China FTA on the bilateral trade, based on trade intensity calculation and a gravity model simulation, and formulates scientific and reasonable countermeasures based on research findings. The empirical analysis conducted in this research finds the following: the large amount of trade between the two countries is closely related to the level of the economic development (GDP) of the two countries. Most of all, the distance between the two countries, the per capita GDP of the two countries and whether FTA is established all affect the trade volume. While the distance between the two countries has a negative correlation with the trade volume, the other variables have a positive correlation. From this analysis, we draw several policy suggestions, focusing on how to resolve trade disputes between Korea and China, to further promote comprehensive cooperation, to accelerate the structural adjustment of industries, and to promote bilateral trade. Hopefully, the findings and policy suggestions from this study may contribute to the sustainable development of the Korea-China FTA.
