摘要:

以环渤海16个城市的临港石化产业为研究对象,采用修正的EG指数和产业间协同集聚指数对其2003年和2013年的集聚程度进行测算,利用空间计量模型测度其集聚效益,最后通过对比集聚类型、集聚程度和集聚效益对环渤海地区临港石化产业的集聚水平进行综合评定。主要得出以下结论: 根据EG指数取值的正负与企业的规模经济水平,将集聚分为地理空间的“区域集聚”和市场空间的“规模集聚”。2003和2013年环渤海地区临港石化产业以“区域集聚”类型为主。 2003年和2013年环渤海地区临港石化产业均为低度集聚,除了一些城市的集聚程度和产业间协同集聚程度得到提高外,大部分城市都有所降低。 经过10 a的发展,环渤海地区临港石化产业的空间相关性加强,集聚效益有所提高,但集聚对产业劳动生产率不存在稳定的正向空间影响。 环渤海地区临港石化子产业集聚水平由高到低依次为石油加工、炼焦与核燃料加工业,橡胶和塑料制品业,化学纤维制造业,医药制造业,化学原料和化学制品制造业。

Abstract:

Agglomeration in port areas has been a significant characteristic of the petrochemical industry in recent years. Taking the 16 cities in the Bohai Sea Rim region as examples, this article uses the EG index to measure the agglomeration level of the port petrochemical industry in 2003 and 2013, and employs the Spatial Econometric Models to test the spatial effect of agglomeration on industrial efficiency. Eventually this article measures the agglomeration level of the port-petrochemical industries by comparing the agglomeration types, degrees and efficiency. The main conclusions are as follows: 1) According to the positive and negative of the EG index and the scale of the enterprise's economies of scale, the agglomeration is divided into two types: the "regional agglomeration" and the "scale agglomeration". In 2003 and 2013, most of the petrochemical industries in the area around the Bohai Sea belong to the type of "regional agglomeration". 2) In 2003 and 2013, the degrees of the petrochemical industries in the area around the Bohai Sea are low. Overall, in 2013, the degrees of agglomeration and co-agglomeration were lower than that in 2003. But there are still some cities and sub industries’ degrees are higher or improved. 3) After the development of 10 years, the spatial correlation of the petrochemical industry is strengthened. Agglomeration has no steadily positive effect on the labor productivity of the petrochemical industries. But generally speaking, in 2013, the agglomeration efficiency was improved compared to 2003. 4) The petrochemical industry in the Bohai Sea Rim region has advantages in the manufacture of rubber and plastics products and manufacture of raw chemical materials and chemical products industries.

Key words: the port petrochemical industries, agglomeration level, agglomeration type, agglomeration efficiency, the Bohai Sea Rim region
