Abstract
The development of marine economy has stimulated the need for marine natural products and services, as well as the demand and utilization intensity of marine resources. As a result, the coastal regions start to discharge more and more pollutants, posing a serious threat to marine ecoenvironment. Because of the interactions between marine economy and marine ecology, it is of practical significance to study the marine economic-ecological complex system (MEECS). However, the relevant studies have several common defects: the incomplete data statistics system, the limited attention on development law or action mechanism, and the lack of long-term quantitative and empirical analysis. To overcome these defects, this paper tries to measure the coordinated and coupled development (CCD) and evaluate the sustainable development of MEECS. Specifically, an ecology-dominated coordinated development model was proposed for the complex system, and a differential equation model was established to describe the dynamic coordinated development of the complex system. Through data envelopment analysis (DEA), the sustainable development of the complex system was evaluated based on its input-output efficiency. Through experiments, the outputs of decision-making units (DMUs) of our model were obtained, and the development of the subsystems in MEECS was evaluated comprehensively to verify the effectiveness of our algorithm.

The coastal regions in China discharge more and more pollutants, which seriously threat the marine ecoenvironment. erefore, it is of practical significance to measure the coordinated and coupled development (CCD) and evaluate the sustainable development of the marine economic-ecological complex system (MEECS) [5,6,7,8,9,10]
Summary
Received July 2021; Revised August 2021; Accepted 24 August 2021; Published 7 September 2021. The relevant studies have several common defects: the incomplete data statistics system, the limited attention on development law or action mechanism, and the lack of long-term quantitative and empirical analysis To overcome these defects, this paper tries to measure the coordinated and coupled development (CCD) and evaluate the sustainable development of MEECS. Erefore, it is of practical significance to measure the coordinated and coupled development (CCD) and evaluate the sustainable development of the marine economic-ecological complex system (MEECS) [5,6,7,8,9,10]. To overcome these defects, this paper tries to measure the CCD and evaluate the sustainable development of MEECS. Where whether uij and uji are greater than zero determines the type of competition between subsystems. (1) If both uij and uji are greater than zero, the i-th and j-th factors are pure competitors. e development of one factor is Orderliness
