Temporal and spatial evolution and influencing factors of the port system in Yangtze River Delta Region from the perspective of dual circulation: Comparing port domestic trade throughput with port foreign trade throughput

Under the new development pattern of “dual circulation” in China, it is of great theoretical and practical significance to study the spatial pattern and evolution law of port systems. This study takes the port system in the Yangtze River Delta Region (YRDR) as an example, based on the panel data from 2000 to 2019, analyses the spatial pattern and evolution characteristics of port domestic trade throughput (PDTT) and port foreign trade throughput (PFTT) from the perspective of dual circulation. The key influencing factors in the evolutionary process are explained, and the spatio-temporal evolution characteristics of the two types of port throughput are compared. The results show that (1) in spatial evolution, the PDTT and PFTT of the port system in the YRDR fluctuate and increase significantly, showing a typical three-level echelon structure in space. (2) From the perspective of spatial equilibrium, the two types of port throughput are markedly discrete; however, the degree of agglomeration of PFTT is greater than that of PDTT. (3) In spatial patterns, the centers of gravity of PDTT and PFTT are distributed in Suzhou and Jiaxing, respectively. Both are distributed from northwest to southeast. However, the rotation angle of PFTT was larger, and the north-south differentiation was more evident than that of PDTT. (4) In influencing factors, the throughput pattern of the port system in the YRDR is driven by multiple factors, and some differences exist in the driving mechanism between PDTT and PFTT.

Coastal landscape changes at Unguja Ukuu, Zanzibar: Contextualizing the archaeology of an early Islamic port of trade

Unguja Ukuu, located on the Zanzibar Archipelago, eastern Africa, was an active Indian Ocean trading settlement from the mid-first millennium until the early second millennium AD. As part of recent archaeological excavations aimed at understanding the site’s transregional trade networks, geoarchaeological analyses were undertaken to document the geomorphic context of the ancient settlement. Here, we outline the results of these field and laboratory studies to discuss patterns of anthropogenic sediment deposition. Unguja Ukuu’s deep coastal stratigraphy appears to record progradation of an inhabited back-reef shore from the mid-seventh to the nineth centuries AD, perhaps in the wake of an earlier middle to late Holocene marine transgression. Excavations on the back-beach show that deposits associated with the ancient settlement include interlayered middens, paleofloors, and backshore sands and, in later phases, a peri-urban dump with dark-earth-type anthrosols developed on these deposits. Coastal progradation appears to have been driven in part by the accumulation of anthropogenic detritus and compaction of ancient surfaces. We hypothesize how the inherited, submerged relic Late Pleistocene geomorphology of the intertidal zone and later Holocene sediment supply from the hinterland may have supported the emergence of Unguja Ukuu as a trading locale, and possibly contributed to its decline in the early second millennium AD.

Research on transport and weathering of oil spills in Jiaozhou Bight, China

Jiaozhou Bight is a semi-closed embayment, located on the eastern coast of Jiaodong Peninsula. Qingdao Port located in the bight is one of the largest transportation trade and professional crude oil transportation ports in China. Potential oil spills will cause serious damage to the local ecological environment and lead to huge social and economic losses. In this study, the hydrodynamic model of Jiaozhou Bight was established and its accuracy was verified based on the tidal current data of Qingdao Port and Huangdao Station. The oil spill model of Jiaozhou Bight was constructed by coupling with wind, tidal current and other environmental fields. Taking the “11.22” Huangdao oil spill accident as a case, the accuracy of the developed oil spill model was verified. The key factors affecting oil spill movement in Jiaozhou Bight are found out and the influences of wind regime, tidal current, oil spill source location and oil spill amount on drift and diffusion movement are researched. The effects of wind speed and other factors on weathering of the oil spill are studied. The research results can provide technological supports for making emergency responses to the oil spill in Jiaozhou Bight.

Influence of dry ports construction on seaport growth: Case of Ningbo Zhoushan Port

Despite the vigorous development of dry ports, there is a lack of evaluation on the practical effects of dry port projects. Considering Ningbo Zhoushan Port as an example, this study employs a Difference-in-Differences approach to investigate the effect of dry port construction on the growth of seaports in China. China Customs foreign trade container data and Chinese prefecture-level city panel data are utilized in this study. Further, the mediation model is used to investigate the impact mechanism of dry port construction on city-port container flows. The findings show that the construction of the dry port has significantly promoted the growth of the city-port container volume, which has increased by 31.5%. Such an impact depends on foreign trade growth and port substitution effects. Thus, the results provide support to the government and port stakeholders in clarifying the benefits and influence channels of dry port construction, ultimately promoting port growth and inland economic development.

The Role of Trade in the Conversion to Islam and in the History of the Volga Bulghars

The trade-network of Afro-Eurasia changed radically in the 9th–10th centuries, instead of the former east-west routes the south-north came to the fore. The Volga-Kama region became the most important port of trade between the Islamic world and Eastern Europe in the beginning of the 10th century which set in motion the formation of the Volga Bulghar state and the conversion to Islam. The Volga Bulghars are mentioned in the Muslim sources as the center of trade. Ibn Faḍlān, al-Masʿūdī give a detailed picture of this intensive trade. The Muslim dirhams came from Samanid mints to the Volga region and the Volga Bulghar merchants bought northern merchandise (furs, slaves, wax, honey etc.) in the 10th century. Al-Muqaddasī gives an exhaustive list of trade goods from the Volga Bulgar area at the end of the 10th century. After the disappearance of the silver dirhams in the first decades of the 11th century the state of the Volga Bulghars remained a significant trade center. The Muslim maps of Ibn Ḥawqal, Maḥmūd al-Kāshġarī and al-Idrīsī reflect a river system called Etil which is waterway commercial network. It connects Central Asia via Siberia with the Volga-Kama region, the northern regions can be reached on the way along the Kama and perhaps the Vyatka, the northeastern network includes the Oka, Unzha and upper Volga. The southern routes represent the lower Volga from the territory of Volga Bulghars to the Caspian Sea and the Volga-Don portage plus the lower Don until its estuary to the Azov Sea.

In order to explore the comprehensive land carrying capacity of Hainan Island, based on the statistical data from 2009 to 2019, the TOPSIS and GM (1.1) models were used to evaluate and predict the comprehensive land carrying capacity of Hainan Island from 2020 to 2030 from time series perspective. In addition, ArcGIS software and obstacle degree model were used to conduct dynamic analysis and obstacle degree diagnosis of the comprehensive land carrying capacity of cities and counties in 2015 and 2019. The results show that the comprehensive land carrying capacity of Hainan Island is mainly affected by the economic and social subsystems. Although the level of comprehensive land carrying capacity fluctuated from 2009 to 2019, it showed a slow upward trend as a whole. The closeness value of water and soil resources and ecological environment subsystem showed a downward trend, while the closeness value of economic and social subsystem increased significantly. The prediction results show that the comprehensive land carrying capacity shows a continuous upward trend in 2020-2030. There are significant differences in the spatial dynamic changes of the comprehensive land carrying capacity. The overall performance is that the comprehensive carrying capacity of coastal cities and counties is higher than that of inland cities and counties. In 2015 and 2019, Haikou and Sanya were at a high level. Eight cities and counties were at the medium level in 2015, 11 cities and counties in 2019. And 8 cities and counties were at the low level in 2015, while only 5 cities and counties in 2019 and the sub-system carrying capacity of each city and county was significantly different. The analysis of obstacle degree shows that the economic subsystem had the highest obstacle degree in 2015 and 2019. In 2015, the obstacle factors mainly included economic density (X9), fixed asset investment per land (X12), effective irrigation rate of cultivated land (X6) and GDP per capita (X8). In 2019, the main obstacle factors were economic density (X9), fixed asset investment per land (X12), GDP per capita (X8) and multiple cropping index (X14). The level of economic development is the main factor restricting the comprehensive carrying capacity of land in cities and counties. This word is expected to provide the scientific basis for ecological conservation and economic sustainable development in the construction process of Hainan Free Trade Port. 参考文献 相似文献 引证文献

Trade Activities and the Spread of Christianity by Portugal: Port of Faifo (Vietnam)

In the 16th and 17th centuries, Faifo (Hoi An, Quang Nam province) emerged as one of the busiest international trading ports in Southeast Asia in general and in Vietnam in particular. At the same time, in Europe, Portugal and its formidable navy discovered a new maritime route to Asia. Using this knowledge, the Portuguese became one of the first Western states to explore this part of the world and laid the foundation for trade and missionary activities in a number of different countries and locations there. Among them, Faifo (in Vietnam) was a notable example. In fact, for almost a century (from the second half of the 16th century to the middle of the 17th century), the Portuguese had established business relationships and played an important role in trading activities in Faifo. Meanwhile, the Portuguese Crown strongly supported the Jesuit priests, aiding them in becoming the first Catholic missionary force based in Vietnam, thereby allowing for the introduction and spread of Christianity in Faifo as well as in other locations around Cochinchina. However, at the end of the 17th century, for a number of different factors, Portugal gradually lost its important role in trading and missionary activities in the port of Faifo. This article examines the Portuguese commercial and missionary activities in Faifo in the 16th and 17th centuries. It also aims to make a specific contribution to clarifying the relationship of exchange between Vietnam and Portugal in the 16th and 17th centuries.

Implication and development of the legal system of the pilot free trade zones with Chinese characteristics

Ever since its birth, the legal system of the Pilot Free Trade Zones with Chinese characteristics has face a relatively severe external environment and realistic internal motivation. Through the exploration of institutionalizing authorized legislation, the legal system of the Pilot Free Trade Zones has formed a multi-level normative system. Five areas represented by investment system reform, trade facilitation, financial reform, administration, and dispute settlement mechanisms constitute the core contents of the legal innovation of Pilot Free Trade Zones with Chinese characteristics. The legal system of the zones is a top-level design of China’s response to the complicated international background, the inevitable requirement to promote institution-based opening-up, the centralized embodiment of high standard economic and trade rules, the inevitable way to improve social and global governance, and the experimental field to promote the practice and innovation of the rule of law reform. With the upgrade and expansion of Pilot Free Trade Zones, the establishment of Hainan Free Trade Port, the zones face corresponding challenges of capacity upgrade, replication and promotion, and pilot acceleration, which need to further expand the function of integrated innovation, in line with the international economic and trade standards, to promote deepening reform and achieve high quality development. The rule of law construction in China’s pilot free trade zones should adhere to the combination of the positioning of the rule of law and problem orientation, further clarify the positioning of the rule of law in the pilot free trade zones under the conditions of high-level opening up, and strengthen the state’s top-level design for the legislation of the pilot zones across the country. Focus on the implementation and promotion of the rule of law construction in China’s pilot free trade zones.

THE PORT BUSINESS PROCESS ANALYSIS AS THE MANAGEMENT MODEL

Abstract.The research presented in this article is aimed at developing a methodology for decomposing business processes that take place in the port, into components and finding optimal approaches to their management within the port enterprises. The aims are to carry out a schematic grouping of operations and management decisions of port operators by management areas and to analyze the role of business processes in achieving enterprises commercial goals. Different approaches to structuring business processes are consi-dered, and the methodology used in this article, based on UML (Unified Modeling Language), is chosen, as it is a powerful analytical method for creating charts from different data and information sources. Based on the analysis of port operators of Ukrainian sea trade ports, a general profile of the port operator has been deve-loped, which reflects the evolution of business processes of maritime transport enterprises from one of the simplest forms to another, which is a typical modern transport enterprise.The article is devoted to the main trends in the work of Ukrainian seaports. The importance is emphasizedensuring the manageability of such a complex system as the maritime transport enterprise, and emphasizes the importance of identifying specific business processes specific to port enterprises, and highlighting the specifics of the analysis of general business processes. Based on the analysis of opportunities for growth of exports, imports and transit, it was determined that the greatest potential for further development of port operators is to expand the cargo base and attract transit cargo, so the emphasis is on building relevant business processes. The main reasons for restructuring or transformation of the business model of the enterprise are identified. The main sectors of restructuring of the port operator's business model have been identified.Keywords: port, port operator, business process, cargo turnover, transit.

Research on Decorative Patterns of Doors and Windows for Historical Architecture in Macau

As the commerce and trade port for cultural exchange between China and Portugal, in modern times, Macau was endowed with all-inclusive, abundant and diverse historic features. After the historical architecture in Macau was made world heritage in the year of 2005, there was a new trend for studying Macau architectural culture at home and abroad, many of which were related to the architectural decorative patterns, but less emphasis was laid on the decorative patterns of doors and windows. Under the influence of the concept of “the house is crowned by the door” for Chinese architectural culture, as the important medium between internal space and external information of architecture, the decorative patterns of doors and windows reflect the spiritual symbol and humanistic characteristics of architecture itself in an even better fashion, presenting significant social historic values.

Connotation, Composition, and Characteristics of Location Value of Free Trade Port—An Empirical Study of Ningbo Zhoushan Port

The concept of “location value of free trade port” is put forward for analysis and research, which is defined as the economic capacity and value of the port jointly determined by the natural resources, economic level, and social and cultural environment of the free trade port, which has a sustainable development value created based on the advantages of the port itself and combined with factors such as culture, policy, science, and technology. The analysis shows that economic and economic support, political system, industrial development, cultural heritage, innovation, and technological level are the basic components of location value, and the location value of free trade port is characterized by openness, innovation, sustainability, boundary, and dependence. This paper finally summarizes the mining direction of the location value of the free trade port: such as accelerating the transformation and upgrading of the service industry, paying attention to building sustainable development, which provides a new perspective for the free trade port to enhance its location value.

Weak Ties and Strange Attractors:Anomalocivitasand the Archaeology of Urban Origins

This paper offers three figures of thought for research on the origin of urban places and societies. As an alternative to linear, evolutionary models of urbanization, I propose to see the formation of urbanism as an evolving field guided by ‘strange attractors’, which tend to converge towards particular constellations of practices and institutions. In this view, the study of ‘odd’ urban sites and societies, anomalocivitates, which have reached unusual constellations, can be revealing. A key attractor for urban societies is so-called ‘weak ties’, connections that reach beyond close social clusters. I suggest ways to study urban sites from the point of view of evolving social networks. To illustrate these concepts, the paper discusses coastal and riverine trading ports, emporia in northern Europe in the eighth-tenth centuries ad.

PLACE ATTACHMENT STUDY IN KUTA BEACH COMMERCIAL CORRIDOR

Kuta Beach has undergone a change in function and a shift in activity which began with the opening of the trading port function to become a popular beach tourism area in Bali. The development of tourism on Kuta beach is currently experiencing a very drastic increase as evidenced by the very rapid development of tourist accommodation and infrastructure arrangement by the government. The increase in the number of hotels, inns and various other types of functions indicates the high interest in investment in the Kuta beach road area. Indirectly, this dynamic changes one's bond in the Kuta Beach corridor. The study of Place attachment in the commercial corridor area of Kuta Beach aims to determine the important factors in the formation of a place's identity, corridor characteristics, visitor preferences, activity studies, and magnetic identification of an area. The research method in place attachment studies in the Kuta beach corridor uses a quantitative approach accompanied by a qualitative descriptive explanation to find out the phenomena and perceptions of visitors. Knowing the important variables and elements in the corridor becomes the focus of the study to obtain data on the level of place attachment that exists in the commercial corridor of Kuta beach. Based on the literature study, the place attachment study is one of the cornerstones in assisting the planning of an area by assessing the level of attachment to a place.
