Economic Wheel – Economic Concentration Degree and Regional Economic Diversification Indicator System 经济之轮 – 经济集中度与区域经济多元化指标体系


Economic Wheel – Economic Concentration Degree and Regional Economic Diversification Indicator System
经济之轮 经济集中度与区域经济多元化指标体系





1.      Introduction

In economic work, we often talked about product diversification, market diversification. In the economy, all industries have to be developed simultaneously, so as to achieve the so-called "one flower alone is not spring, all flowers flourishing make a full spring garden" situation. The problems involved here can be theoreticized into product economic structure, market economic structure and industry economic structure in economics. This also belongs to regional economic balance property, which is the balance property of regional economic diversification. Based on this, here I proposed Beizhan regional economic diversification theory and indicator system. The diversification of the industries included here is just the industry balance property of the regional economy.

2.      Existing Concept

2.1.      Industry concentration

“Industry concentration degree (Concentration Ratio), also known as industry concentration ratio or market concentration ratio (market concentration rate), refers to the sum of the market shares of the largest N enterprises in a certain industry (production value, production volume, sales total, sales volume, total number of employees, asset total, etc..), it is the measurement indicator for the whole industry market structure concentration degree,  it is used for evaluating the difference of enterprise quantity and relative scale, it is an important quantitative indicator of the market forces.” [1]

2.2.      Hirschman index

Hirschman index is based on the industry's total number of enterprises and the scale of distribution, which is the sum of the square of market share of the market contribution of all enterprises on the relative market.” [2]

2.3.      Entropy index

Entropy index (simplified as E index) borrows the concept of entropy in information theory, with the meaning of the average amount of information; its definition is as the formula below:

        N
EI = ΣSi(log(1/Si)
       i=1

EI is the entropy index; Si is the market share of the i-th enterprise (sales total or added value, etc.); n is the total number of enterprises in the market. ” [3]

These existing indicators are not comprehensive enough, not simple enough, focusing and rationality are also questionable.

3.      Beizhan Regional Economic Diversification Theory

Beizhan regional economic diversification theory mainly refers to Beizhan regional economic diversification indicator system.

1.   前言

在经济工作中,我们也经常提到产品多元化,市场多元化。在经济上要百业并举,实现所谓的“一花独放不是春,百花齐放春满园”的局面。这里所涉及的问题在经济学中就可以理论化为产品经济结构,市场经济结构和行业经济结构,这也属于经济均衡性,是经济多元化的均衡性。基于此,我提出备战区域经济多元化理论及指标体系。这里所包括的行业的多元化就是区域经济的行业均衡性。

2.   现有的概念

2.1.      行业集中度

行业集中度(Concentration Ratio)又称行业集中率或市场集中度Market Concentration Rate),是指某行业的相关市场内前N家最大的企业所占市场份额产值、产量、销售额、销售量、职工人数、资产总额等)的总和,是对整个行业的市场结构集中程度的测量指标,用来衡量企业的数目和相对规模的差异,是市场势力的重要量化指标[1]

2.2.      赫希曼指数

“赫希曼指数是指基于该行业中企业的总数和规模分布,即将相关市场上的所有企业
市场贡献的市场份额的平方后再相加的总和”[2]

2.3.      熵指数

“熵指数(简称E指数)借用了信息理论中熵的概念,具有平均信息量的含义,其定义公式为:

        N
EI = ΣSi(log(1/Si)
       i=1

EI为熵指数;Si为第i企业的市场份额(销售额或增加值等);n为该市场中的企业总数。” [3]

这些已有的指标都不够全面,也不够简单,针对性和合理性也值得商榷。
