宁德地区养殖大黄鱼市场结构特征的初步分析

Preliminary analysis of the market structure of the farmed large yellow croaker in Ningde

采用贝恩的市场结构分类法,对宁德地区养殖产地的市场结构类型、产业市场集中度和产业进入壁垒进行了分析,确定了宁德地区大黄鱼养殖产业的市场结构。研究结果表明:宁德农户养殖的市场集中度指标CR4约为0.87%,市场集中程度很低,处于Ⅵ原子型——不存在集中现象;20余家较大规模养殖企业的CR4约为12.55%,也为Ⅵ原子型;市场竞争性强,接近完全竞争市场;产业进入壁垒较低。得出的基本结论是:产地市场的养殖产业内部集中度较低(Ⅵ原子型),应提高产业内部的集中度;竞争性强,接近完全竞争市场,应控制过度竞争以提高环境资源的配置效率;进入壁垒弱是导致集中度低和完全竞争市场结构的主要原因。

This paper applies Bain＇s market structure classification,analyzes the market structure,industry market concentration degree and the entry barriers in Ningde breeding habitats area,and it identifies the large yellow croaker breeding industry market structure in Ningde.The results show that： Ningde farmers＇ market concentration index of CR4 is 0.87%,the degree of market concentration is very low at Ⅵ atomic type-hardly exists concentration;more than 20 large enterprises＇ CR4 is about 12.55%,also the Ⅵ atomic type;market competition is tense,it is close to the completely competitive market;the industry entry barriers are low.The basic conclusions are： the origin breeding market of internal industry presents lower concentration（Ⅵ atomic type）,so that improving the industry concentration degree is necessary;due to the completely perfectly competitive market,we should control the excessive competition in order to improve the resources allocation efficiency;the weakness of barriers to entry is the leading cause of low concentration and the complete competition market structure.
