polis n.(pl. poleis ) (古希臘的)城邦。

In this section , applying the method , from abstract to specific and from history to present , it analyzes the operation mechanism of urbanization economy affected by market mechanism ; puts forward four theories of urbanization economy from economic perspective , including agriculture surplus and comparison advantage ; non - agricultural industry ; agglomeration economy and spillover effect , on this basis of the theories , it , on one hand , analyzes two kinds of internal mechanism in the chronologic operation of urbanization economies : increasing mechanism of urbanization economies in urban output industry ; and changing mechanism from specialization to integration , which are the representations of the evolution of “ mart “ development ; on the other hand , it analyzes two internal mechanism of dimensional operation of urbanization economy : internal spatial enlargement mechanism of urbanization economies from monocentric city to multi - center city , and external spatial enhancement mechanism which represents city - regionalization and city - chain connection , the later two mechanism represent the evolution of “ polis “ development 這一部分,按照由抽象到具體和由歷史到現代的研究方法,分析了市場機制作用下的城市化經濟運行機理,從經濟學角度提出了農業剩余與比較優勢、非農產業、聚集經濟、外溢效應四大城市化經濟定理;在此基礎上,一方面分析了城市化經濟運行沿時間增長的兩個內在內容提要機制:城市輸出產業的城市化經濟增長機制和從專業化到綜合化的城市性質變遷機制,它們主要表現為“市”發展的延續;另一方面分析了城市化經濟運行沿空間增長的兩個內在機制:從單中心到多中心的城市化經濟運行的內部空間擴展機理和表現為城市區域化、城市連綿體的城市化經濟運行的外部空間擴展機理,它們主要表現為“城”發展的延續。

The third section gives the essence of theory , specifying the equilibrium of urbanization economic operation . firstly , it gives definitions of “ polis “ and “ mart “ , which are two aspects of urbani 在此基礎上,定義了由u曲線與y曲線的交點所決定的城市化經濟均衡的概念,并分析了由此表現的城市化經濟運行的均衡態。
