Abstract
With the development of economic globalization, international trade competition is increasingly intensified. As an important hub of waterway transportation, the sustainable economic development of ports has an important impact on the economic development of the entire country. Therefore, the research on the sustainable development of port economy has been paid more and more attention by everyone, but the current results are not ideal. This paper studies the sustainable development of port economies based on networked smart sensor technologies and system dynamics. First, according to the construction principles of the sustainable development index system, combined with the actual situation of the port economy, the evaluation index system layer of the sustainable development of the port economy is divided into four sub-systems: population, environment, resources and economy. A system dynamics model for the sustainable development of the port economy will be constructed and its sensitivity will be analyzed. Then, the above system dynamics model is combined with the optimized K-means algorithm, and the K-means algorithm is used to quickly calculate the required data in the system dynamics model to form an intelligent system dynamics model for the sustainable development of port economy. Finally, this article takes a certain port economy sustainable development giant system as an example, and implements a sustainable development strategy based on the idea of the coordinated development of population, environment, resources and economy. Run the intelligent system dynamics model for the sustainable development of port economy constructed in this research to simulate the dynamics of each subsystem. Experimental results show that in the next 20 years, the total population, number of employed population and employment ratio of the port city will continue to increase. After 2025, the emissions of the Exhaust have been declining year by year, the total amount of resources has been continuously reduced, and the utilization rate of resources can be increased to 80.01%. The growth rate of GDP in 20 years is as high as 18.75%, the ratio of the secondary and tertiary industries has changed, and the tertiary industry has become the dominant one. Therefore, the sustainable development system dynamics model of the port economy based on intelligent algorithms and sensor technology can effectively predict the future economic trend, help adjust strategies and further promote the sustainable development of the port economy.
Highlights
DYNAMIC SIMULATION RESULTS OF RESOURCE AND ECONOMIC SUBSYSTEM 1) RESOURCE SUBSYSTEM Using the resource subsystem in the model constructed in this study to simulate the total resource and utilization rate of the port area, the simulation results are as follows: As shown in Figure 4, as time increases, resources continue to be consumed, and there is no possibility of regeneration after non-renewable resources are used
2) ECONOMIC SUBSYSTEM Using the economic subsystem of the model constructed in this study to simulate the changing trend of the port city’s GDP and the proportion of the output value of the three major industries, the results are as follows: As shown in Table 2, the GDP of the port area has been increasing year by year, with a growth rate of 18.75% in 20 years, which shows that its economic level has been increasing year by year
SUGGESTIONS FOR IMPROVING THE SUSTAINABLE DEVELOPMENT CAPACITY OF PORT ECONOMY In order to improve the sustainable development of port economy, several suggestions are put forward based on the analysis of this article
Summary
A. BACKGROUND SIGNIFICANCE Port is a very important node related to international trade and logistics and an important support for regional export-oriented economy. BACKGROUND SIGNIFICANCE Port is a very important node related to international trade and logistics and an important support for regional export-oriented economy It is one of the basic industries of the national economy and has an important impact on. The associate editor coordinating the review of this manuscript and approving it for publication was Yanjiao Chen. The development of trade and regional economy [1]. With the gradual deepening of the world financial crisis and the aggravation of the energy shortage crisis, the port economy must unswervingly move towards a sustainable development path, which is conducive to the efficient use of port resources, enhances the competitiveness of ports, and promotes the sustainable development of port cities.
