【摘要】：经济活动在空间上的变迁表现为集聚或分散,经济活动在时间上的变化表现为增长或衰退。集聚和增长是经济发展在时空演化过程中最显著的特征,二者紧密联系,相互促进、相互影响。然而,长时间以来,经济学界一直将集聚和经济增长的研究相分离,没有形成一个系统的理论,关于集聚的研究缺乏经济增长的背景而显得单薄,关于增长的研究缺乏集聚的贡献而显得缺憾。直到新经济地理学的出现,才打破了二者长期以来的独立分析的状态,集聚和经济增长开始纳入同一分析框架和体系当中。在此之后,众多学者开始从理论和实证角度对集聚和经济增长的关系进行了广泛而深入的研究,绝大部分研究成果表明:集聚与经济增长之间存在正相关的关系,即集聚能够促进经济增长。城市是人口和经济活动集聚的某个空间范围和载体,城市集聚是所有集聚类型中的最高形态,因为城市集聚包含了人口集聚、要素集聚、产业集聚等等。当城市集聚产生之后,又是什么机制在推动着城市经济的发展或者是区域经济的增长。通过对相关文献和理论进行梳理,厘清城市化、城市集聚、经济增长之间联系,试图从市场机制和非市场机制两个层面来推导城市集聚促进经济增长的作用路径。市场机制主要是指城市集聚通过范围经济和规模经济来实现报酬递增,非市场机制主要是指城市集聚通过知识溢出效应和消费偏好溢出效应来实现报酬递增,在二者的共同作用下,城市集聚促进了经济的增长。长江中游城市群是2015年国务院批复的跨区域国家级城市群,作为中部崛起战略的重要支撑,国家明确对其战略定位为:中国经济新增长极。但是,通过对发展现状的描述发现:与我国长三角、珠三角、京津冀城市群相比,长江中游城市群的城市集聚水平和经济发展水平整体较低。在实证研究中,以劳动生产率和就业密度分别作为经济增长和城市集聚的代理变量,利用城市群内31个城市的10年面板数据进行多元回归,实证结果表明:长江中游城市群城市集聚能够促进经济增长,但整体集聚水平不高,对经济增长的促进作用不明显。
[Abstract]:The change of economic activity in space is agglomeration or dispersion, and the change of economic activity in time is growth or decline.Agglomeration and growth are the most remarkable characteristics of economic development in the evolution of time and space. They are closely related, promote and influence each other.However, for a long time, the economic circles have separated the study of agglomeration from the study of economic growth, and have not formed a systematic theory. The research on agglomeration lacks the background of economic growth and appears to be thin.The research on growth lacks the contribution of agglomeration.It was not until the appearance of new economic geography that they broke the state of independent analysis for a long time. Agglomeration and economic growth began to be brought into the same analytical framework and system.After that, many scholars began to conduct extensive and in-depth research on the relationship between agglomeration and economic growth from both theoretical and empirical perspectives. Most of the research results show that there is a positive correlation between agglomeration and economic growth.Namely agglomeration can promote economic growth.Urban agglomeration is the spatial range and carrier of population and economic agglomeration, and urban agglomeration is the highest form of all agglomeration types, because urban agglomeration includes population agglomeration, factor agglomeration, industrial agglomeration and so on.When urban agglomeration comes into being, what mechanism is promoting the development of urban economy or the growth of regional economy.Through combing the relevant literature and theory to clarify the relationship among urbanization, urban agglomeration and economic growth, this paper tries to deduce the role of urban agglomeration in promoting economic growth from the two aspects of market mechanism and non-market mechanism.Market mechanism mainly refers to urban agglomeration through scope economy and economies of scale to achieve increasing returns, non-market mechanism mainly refers to urban agglomeration through knowledge spillover effect and consumption preference spillover effect to achieve increasing returns.Under the joint action of both, urban agglomeration promotes the growth of economy.Urban agglomeration in the middle reaches of the Yangtze River is a cross-regional state-level urban agglomeration approved by the State Council in 2015. As an important support of the strategy of rising up of the middle part of the Yangtze River, the state has clearly defined its strategic position as: the new economic growth pole of China.However, it is found that compared with the Yangtze River Delta, the Pearl River Delta and the Beijing-Tianjin-Hebei urban agglomeration, the urban agglomeration level and the economic development level in the middle reaches of the Yangtze River are lower.In the empirical study, the labor productivity and employment density are taken as the proxy variables of economic growth and urban agglomeration, respectively, using the 10-year panel data of 31 cities in the urban agglomeration to carry out multivariate regression.The empirical results show that urban agglomeration in the middle reaches of the Yangtze River can promote economic growth, but the overall agglomeration level is not high, and the promoting effect on economic growth is not obvious.
