我国临港产业发展现状及空间分布特征

Current development situation and spatial distribution characteristics of China's port industry

为了合理评估我国临港产业发展现状及空间分布特征,明确我国临港产业发展优劣势,以11省市的61座沿海城市为研究对象,基于投入产出基本流量表和相关方法计算我国各沿海城市的临港产业产值,并从总量、行业角度和城市贡献度进行现状分析,在此基础上进一步采取核密度估计法对我国沿海城市及沿海城市的临港产业的空间分布特征进行分析,并得到空间分布趋势。结果表明,目前我国沿海城市中临港产业较为发达,超过3成城市临港产业产值接近或超越1000亿元规模,其中在长三角和珠三角地区范围内聚集最为密集,61座沿海城市可分为4个层级。

To reasonably assess the current development situation and spatial distribution characteristics of China's port industry and clarify the advantages and disadvantages,this paper takes 61 coastal cities in 11 provinces as research objects,calculates the output value of China's port industry in each coastal city based on the input-output basic flow table and related methods,and analyzes the current situation from the perspective of total volume,industry and city contribution,and further adopts the kernal density estimation method to specify the spatial distribution characteristics of China's port city and port city industry.The results show that the port industry is more developed in China's coastal cities,and the output value of port industry in more than 30%of the cities is close to or beyond 100 billion yuan,among which the Yangtze River Delta and the Pearl River Delta are the most densely clustered.61 coastal cities can be divided into 4 levels.
