advances in Jiangsu and Guangdong has always remained high and developed rapidly. (2) Specifically, during the development period, the comprehensive development index of scientific and technological advancement in the majority of coastal regions exhibited varied degrees of fluctuation. For example, the comprehensive development index of scientific and technological innovation in Tianjin, Liaoning, Shandong, and Guangxi dropped from 0.089, 0.088, and 0.184 in 2016 to 0.082, 0.085, and 0.181 in 2018, respectively. Most of them are caused by changes in the value of an indicator variable in the scientific and technological innovation layer, but the fluctuation range is small, and small-scale fluctuations will not affect the change range of scientific and technological innovation development. Most coastal areas are growing. Among them, the disparity in the level of scientific and technical innovation in coastal regions exhibits a persistent trend of widening. In 2010, the most significant gap in the level of science and technological progress development was only 0.258. In 2018, Hainan, which had the lowest level of technological innovation development, had a technological innovation level of only 0.007. Guangdong, which has the highest level of technological innovation, is as high as 0.523, and the gap widens to 0.516. (3) On the whole, coastal areas have a solid scientific and technological foundation and high scientific and technological innovation efficiency, which promotes the development and improvement in the comprehensive level of scientific and technological innovation in coastal areas. As can be seen from Table 5 and Figure 2, (1) overall, the ecological environment development level in coastal areas basically showed a fluctuating upward trend from 2010 to 2020, which shows that my country's coastal areas fully responded to the national call from 2010 to 2020. The construction of ecological civilization has achieved remarkable results. The ecological environment development and optimization in the coastal areas of Shandong, Hebei, Jiangsu, Jiangsu, Guangdong, and Liaoning has a good level of development and optimization, and the results are relatively outstanding. (2) Specifically, there are varying degrees of fluctuations, but the amplitude is within an appropriate range and ultimately shows an upward trend compared with 2010.
