Abstract

At present, there are few relevant studies on the intensive sea use, and few scholars have provided qualitative and quantitative research examples on the interaction and interaction coupling relationship between intensive sea use and the marine economy. This study constructs comprehensive evaluation indicator systems using the Liaoning Coastal Economic Belt as the research object. The set pair analysis method is used to obtain comprehensive results, and the coupling coordination degree model is employed to carry out an in-depth analysis of the spatiotemporal characteristics of the interaction between intensive sea use and the marine economy. The results show the following. (1) The six cities in the Liaoning Coastal Economic Belt exhibited a fluctuating upward trend in the composite index for intensive sea use, but the intensive sea use level differed among the cities. The intensive sea use level of Huludao was the lowest among the six cities. (2) All cities in the Liaoning Coastal Economic Belt witnessed an upward trend in the marine economy development index, and the gaps between the cities gradually narrowed. The marine economy development index was ranked from top to bottom as follows: Jinzhou, Panjin, Dalian, Yingkou, Dandong, and Huludao. (3)The coupling coordination degree between intensive sea use and marine economy development was relatively stable in Dalian, Jinzhou, Yingkou, and Panjin, ranging approximately from 0.76 to 0.96, which indicates that the four cities witnessed good coordination between sea area utilization and marine economy development. The coupling coordination degree of Dandong and Huludao were relatively low, and Huludao consistently witnessed a low value.

Highlights

With the launch of the “Maritime Power Strategy” and “Maritime Silk Road Initiative,” Chinese coastal provinces have begun to increase the utilization intensity of sea areas, gradually leading the marine economy to provide an important impetus for China’s economic growth [1]

The intensive sea use level of Huludao was the lowest among the six cities. e development of the marine economy in the Liaoning Coastal Economic Belt accelerated. e adjustment of its sea use structure and the increase of sea input led to a rise in the intensive sea use index of the six cities, but the overall rise was small. e composite index for intensive sea use in Huludao was the lowest for a long time due to the low sea use structure index. e coastline of Huludao is 261 km long, starting from Laohekou in Shangkanzi Village, Tashan Township, Lianshan District in the east to the Hongshi Reef in Mengjia Village, Wanjia Town, and Suizhong County in the west

Summary

Introduction

With the launch of the “Maritime Power Strategy” and “Maritime Silk Road Initiative,” Chinese coastal provinces have begun to increase the utilization intensity of sea areas, gradually leading the marine economy to provide an important impetus for China’s economic growth [1]. E resources in these areas are extensively developed and utilized, and the scale of sea reclamation used for industry and town construction has grown rapidly, resulting in inappropriate investment and a serious waste of marine resources [2]. Offshore sea areas have witnessed a decline in the Complexity potential for development and utilization as well as the capability of sustainable development. Erefore, it is necessary to explore the optimal allocation and utilization structure of sea areas, protect the marine ecological environment, economize and intensively utilize marine resources, and correctly understand the interaction between marine economic development and the utilization of sea areas. Offshore sea areas have witnessed a decline in the Complexity potential for development and utilization as well as the capability of sustainable development. e ocean is both a common space and a valuable source of wealth for human society that is essential to its survival and sustainable development. erefore, it is necessary to explore the optimal allocation and utilization structure of sea areas, protect the marine ecological environment, economize and intensively utilize marine resources, and correctly understand the interaction between marine economic development and the utilization of sea areas. is is a key issue that affects the sustainable development of the marine economy, which requires coordination and balance between marine development and marine protection. is is of great significance for promoting the sustainable development of the region and ensuring the implementation of an integrated strategy for land and sea
