摘要(Abstract):

建设海洋强国,需要依靠海洋科技创新,当前我国面临着实施海洋科技创新战略的迫切性,而明确区域海洋科技创新差异是实施该战略的关键。建立了指标体系并基于因子分析来反映我国沿海11省市的区域海洋科技创新差异,利用探索性空间数据分析(ESDA)和标准差椭圆(SDE)分析区域海洋科技创新水平存在的差异及其时空格局演变,以期对我国海洋科技创新战略的实施具有参考意义。结果表明:(1)从海洋科技创新投入产出情况和海洋科技创新环境方面来看,我国区域海洋科技创新存在明显差异;(2)区域海洋科技创新能力表现出空间负相关性,呈现出空间扩散的态势;(3)区域海洋科技创新差异的空间分布主要向北移动,但区域拉动作用不足。
Construction of a maritime power needs to rely on marine science and technology innovation. China is currently facing the urgency of implementing the marine science and technology innovation strategy,and the key to the implementation of the strategy is to make clear the differences in the regional marine science and technology innovation. This paper establishes an index system and reflects the differences of regional marine scientific and technological innovation in 11 coastal provinces and cities of China based on the factor analysis. The paper uses the Exploratory Spatial Data Analysis(ESDA)and Standard Deviation Ellipse(SDE)to analyze the regional marine science and technology innovation difference and its spatial and temporal evolution.The result shows that:(1)from the aspect of input and output of marine scientific and technological innovation and innovation environment of marine science and technology, there are obvious differences in the regional marine scientific and technological innovation in China;(2)the level of regional marine science and technology innovation shows a negative correlation, with a trend of spatial diffusion; and( 3) the spatial distribution of regional marine scientific and technological innovation difference mainly moves northward,but the regional pulling role is insufficient. It is hoped that this article would be of some useful reference for the implementation of China's marine science and technology innovation strategy.
