摘　　要：为深入推动沿海地区实现高质量发展,以有力支撑和助推中国式现代化,发展新质生产力已成为内在核心驱动力与战略要点。文章聚焦新质生产力的基本构成要素:新劳动者、新劳动对象和新劳动资料,构建中国沿海地区新质生产力的评价体系,以量化沿海地区新质生产力的发展水平及其影响因素。首先,运用熵权TOPSIS模型测度沿海地区的新质生产力发展水平;其次,将测算结果作为集成学习模型的先验训练样本进行训练测试。此外,文章还引入SHAP模型进行可视化分析,以揭示各指标对新质生产力的影响程度。研究结果表明:(1)沿海地区新质生产力水平随时间推移稳步上升,但整体水平较低;(2)地区间发展不均衡显著,东部海洋经济圈领先,形成阶梯式分布格局,且区域差异随时间扩大,但极化现象有所缓解;(3)沿海地区新质生产力水平的提升是科技创新、数字经济、人才培养、绿色低碳发展等多因素共同作用而产生的结果。In order to promote the high-quality development of coastal areas,and to strongly support and promote Chinese modernization,the development of new quality productive forces has become an intrinsic core driving force and strategic point.This paper focuses on the basic components of new quality productive forces:new labourer,new object of labour and new means of labour,and constructs an evaluation system of new quality productive forces in China's coastal provinces,in order to quantify the level of development of new quality productive forces in coastal areas and its influencing factors.Firstly,this paper applies the entropy-weighted TOPSIS model to measure the development level of new quality productive forces in coastal provinces;secondly,the measurement results are used as the a priori sample pairs of the integrated learning model for training and testing.In addition,this paper introduces the SHAP model for visual analysis to reveal the degree of influence of each indicator on the new quality productive forces.The results show that:(1)the level of new quality productive forces in coastal provinces rises steadily over time,but the overall level is low;(2)the development imbalance between regions is significant,with the Eastern Oceanic Economic Circle leading the way,forming a stepped distribution pattern,and the regional differences widen over time,but the polarization phenomenon has been mitigated;(3)The increase in the level of new quality productive forces in the coastal area is the result of a combination of factors such as scientific and technological innovation,digital economy,talent training,green and low-carbon development,etc.
