MEASUREMENT OF PORT CITIES – A SYSTEMATIC LITERATURE REVIEW APPROACH

and on topics related to the maritime industry. provides the results of the latest research and analysis on foreland, seaports and the hinterland. It also explores substantial topics, including logistics, policies, operations, management and navigation related to three main agenda — ocean activities, seaports and the hinterland. ABSTRACTA port city is a city that engages in port and maritime activities and also develops land and maritime economic activities. However, the concept or the tools to measure whether a seaport has achieved the criteria of port-city is still lacking. This paper aims to identify the port city measurement and to propose a novel framework for extending port city development as a tool to improve the maritime tourism sector. This paper adopted a traditional systematic literature review (SLR) with content analysis to code the outcome. The final results indicate that only seven articles validated outcomes from the Scopus database. Based on the global view outcome, there are only six main clusters and 27 sub-factors influencing the development of port cities. The six main clusters were: port characteristics; the awareness of maritime stakeholders, port intensity, vessel characteristics, information technology, and the government’s role. The new strategies could lead to a digitalization of decision-making methods in smart maritime tourism in port city development.


Introduction
A Port city is a city carrying out maritime activities and developing economic activities between the land and the offshore interface. The cultural, social, and economic life of the cities in which ports are located, as well as the links that ports provide to the rest of the world, are all significantly impacted by the presence of the ports . Ports are essential to the growth of an economy because they make it easier to conduct business and add something of value to both the port and the city. This, in turn, increases the opportunities available to regional, national, and even international companies that have their headquarters there (Rodrigue & Schulman, 2017;Jeevan et al., 2022). As major actors in the cultural, social, and economic life of cities, Ports provide economic wellbeing and support a strong identity for those cities and their local communities. This is because ports are major players in the life of cities (Angela & Rodrigo, 2020;Zain et al., 2022).
Many cities have increased their port operations by expanding onshore through land reclamation into the sea. Many more cities have invested significantly in infrastructure serving port areas, such as enlarged industrial areas, expanded highways, or improved access to intermodal alternatives, such as ship-to-rail terminals.
Moreover, the impact of ports on a city economy can be measured through the direct effects concerning the cargo volume, actual employment and gross value related to the activities carried out in the port area; the backward linkages, the indirect employment connected with the services to the port area and the forward linkages including those activities which would not take place in the city without the presence of the port (Tan, 2007). These expansions show how many cities have expanded their port operations (Vellinga and De, 2012;Monios et al., 2018).
Ports are essential nodes on the global stage, playing an indispensable part in the conduct of international maritime commerce as well as the transportation of people. Most of the research was conducted to identify the seaport competitiveness, how to improve seaport by integrating Industrial Revolution 4.0 and the impact of COVID-19 on the Journal of Maritime Logistics Volume 2 Number 1, August 2022: 56-67 maritime industry (Salleh et al., 2017;Menhat et al., 2021). In accordance, Zain et al. 2022 also researched the definition of seaport-city integration, the advantages and disadvantages gained by the city from the seaport and vice versa. A strategy to enhance the integration between seaport and city through dry ports was also discussed. Hence, this research was conducted to close the gaps in the preview literature review. This paper aims to identify the port city measurement, and a novel framework for extending port city development as a tool to improve the maritime tourism sector is proposed.

Maritime and Port Cities
Reliance on a single distribution centre and intra-regional trade Cities continue to play an important role in facilitating global trade flows (Verhetsel & Sel, 2008). Corporations are seeking ways to capitalise on new opportunities while also managing their exposure to rapidly changing markets. According to UN estimates, more than half of the world's population now lives in cities, with two-thirds of the world's population expected to live in cities by 2050 (Wang & Ducruet, 2012). City regions will become even more important in the future, especially given that more than half of the world's cities and urban populations are within 100 kilometres of a coastline (Chhetri et al., 2018).
According to population estimates and projections, metropolitan areas worldwide will continue to grow rapidly due to increased urbanisation. As cities grow in size, there is more competition among them to serve as international transportation, logistics, and services hubs, which include the main modes of long-distance transportation, maritime shipping, air passenger services, and air freight services, among others. When we look at the world's most important maritime hubs, we can see that they set a good example. The maritime business services sector significantly contributes to the economies of several major world cities with a strong commercial orientation (Chhetri et al., 2018).
Maritime and commodity trading services are available in many of the world's largest port cities. The presence of shipowners, port-related industry, and general advanced producer services are all related to the location of advanced maritime producer services (AMPS) but not to port throughput flow (Chhetri et al., 2018). To some extent, the concentration of advanced maritime services and the physical movement and movement of goods, ships, and people has resulted in a spatial division of labour. Only a few port cities, including Rotterdam, Houston, Shanghai, Dubai, and Hamburg, have successfully combined physical flows on a large scale in AMPS functions, following in the footsteps of London, New York, Singapore, and Hong Kong (Akhavan, 2017). Economic changes in the twentieth century resulted in the reorganisation of port activities and how they use the land available (Ducruet, 2011). Increasing tensions between urban and port expansion caused some activities to be relocated downstream via port migration processes, resulting in land use abandonment or intense reduction.
Ancient port areas were abandoned, and the city-port connection began to deteriorate. Ports typically paid little attention to activities involving the reclamation of neglected areas, instead allowing them to deteriorate or renting them out to industries unrelated to the port's primary business (Lam & Yap, 2019). Many cities worldwide have developed a complicated relationship with their port because they owe their very existence to them. The issue of sustainability is high on the agenda as cities and ports collaborate to shape their future relationships (Xiao & Lam, 2017

Methodology
Step one -Define keywords

Step two -Preliminary findings: The keywords mentioned above were used to search articles' titles, abstracts, and keywords in the Scopus databases. According to the preliminary results, approximately 58 articles were found in the Scopus database. Table 1 shows the preliminary findings: Step three -Refining the initial results: To further refine the results and improve the quality and interpretation of the results, four criteria were included below: •  Step four-Final results The final results indicate that only 7 articles validated outcomes from the Scopus database Step five -Data analysis The results were subjected to content analysis to explore the measurement of port city development (global view).

Results
Based on the systematic literature review outcome, seven papers were investigated to achieve the aim of this paper. Moreover, the content analysis was used to retrieve the findings from the articles. Table 3 below shows the SLR findings.  Figure 1 below shows the six clusters and 27 sub-factors to measure the port-city development that is required globally. These measurement factors were required to ensure the efficiency of national growth for the successful development of a port city.

Discussion
Ports are transportation hubs on bodies of water, such as the ocean or a river, and are outfitted with waterway intermodal equipment to ensure ships' safe entry and exit. Ports may also be referred to as harbours. By taking into account each of these aspects, the development of the port city harbours the belief that it will be able to make a positive contribution to the economy's growth as a whole. The establishment of a port city, which comes with a variety of advantages, requires the presence of a port as a precondition. Direct output, national income, employment opportunities, and tax revenue are all generated for the city by the production of ports, the operation of ports, and the development of ports; the intensity of the port has a direct correlation to these factors. The expansion of import and export trade, contemporary industry, and contemporary modes of transportation have contributed to the financial success of the world's first port cities and the development of new port cities such as Singapore, Shenzhen, Hong Kong, and Dubai. Apart from that, port characteristics play an important role in port city development. The adequacy of port infrastructure, facilities, and equipment are the most important factor in the development of the port city (e.g., warehouse, crane, berth, telecommunication, breakwater and good water quality). Moreover, integrating with advanced technologies, for example, Augmented Reality, Virtual Reality, Big Data, will progress the development of port-city. In addition, there is a requirement for adequate infrastructure in the area surrounding or close to the port, such as roads, railways, bridges, telecommunications, buildings, spaces, and homes, in addition to specific routes or roads for heavy vehicles. In port cities' development, activities related to cargo handling were thought to be a key generator of local jobs, taxes, and economic activities. According to Chan and Yip (2011), ports in various regions continue to develop their facilities to make them more competitive with those of other regions and to meet the growing demand for sea transport. Some ports have set their sights on becoming the ones with the highest container port throughput in the world.
Apart from that, the government should play an important role in taking care of the environment and any pollutants that could harm the environment. For instance, the government could establish a policy requiring every port to have its environmental department to ensure it is as environmentally friendly as possible. By creating a pollution-free port city, a new maritime tourism sector, known as seaport tourism, can be attracted and developed within the port itself. Seaport tourism, known as an activity, could occur in the port limit, for example visiting the port environment, loading and unloading cargoes, watching vessel berthing and casting off, etc. Furthermore, incorporating elements of the Industrial Revolution (IR) 4.0 in the seaport sector to transform maritime tourism into smart maritime tourism (SMT) is a novel approach resulting from the new wave of digitalisation. The SMT is a solution that is both effective and efficient, and it can help the seaport gain more profits. Figure  2 below summarises the novel framework to extend the maritime tourism market into port city development.

Conclusion
Apart from being centers of economic activities and trade for maritime nations, ports are also fascinating to people because of the activities that go on there. Based on the outcome, six clusters and 27 sub-factors are needed globally to measure port-city development. For a port city to successfully develop, these measurement criteria were necessary to guarantee the effectiveness of national growth. Even when the citing of ports and ports services industries consume much of the foreshore lands and livelihoods of original settlers of port lands, the inhabitants continue to squeeze themselves to fit into what is remaining of their original land space. New skilled and unskilled settlers are still further attracted to the port precinct in search of economic survival. While this influx of uncontrolled people traffic is a symptom of negative externality, it nonetheless shows the love and attraction that people have for ports and port cities.
Given the preceding discussion and recommendation, introducing smart maritime tourism into the economic lives of port cities will not only serve as a booster to the cities' economic lives but the fact that tourists are not permanent residents of the port cities also always the fear of the local populace of potential increased congestion. The tourists must spend money -on their conveyance, feeding, accommodation, sightseeing, shopping, and even medicals. Clearly, huge chunks of these monies go into the host port cities, with many of such cities across the world thriving economically. The reference to the thriving of port cities in Asia and Europe in the literature on account of tourism has revealed a departure from the traditional holiday havens like the Bahamas and the Paris of this world. With the implementation of smart maritime tourism suggested in this paper, a new vista of opportunity for additional income will be opening for port cities to cash in. Future research on the model raise port cities' living standards and return on investment will be conducted.
