城市文明扩展程度，是衡量人类文明现代化进展的关键性指标之一。集体的制度属性从根本上形构了中国现代城市文明的扩展路径，其形构逻辑具体嵌入城市集体与农村集体的互动关系之中。集体的对外排他性，使迁移城镇化模式成为城市文明在大城市进一步扩展的基本路径；集体的强制分配性与对外排他性，使就近城镇化模式成为城市文明向县域扩展的基本路径；集体的对内聚合性，使在地城镇化模式成为城市文明向镇村扩展的基本路径。尽管集体制不乏弊端，但“集体”的虚化，有可能成为中国现代城市文明扩展道路上的阻障。中国在集体制下呈现的城市文明有序扩展路径，是一个肩负后发赶超历史任务的巨型发展中国家，在资源短缺的经济条件约制之下走出的一条独特的文明发展道路。这条道路是中国给世界提供的有别于西方模式的人类文明现代化的另一条出路。

The expansion degree of urban civilization is one of the key indicators to measure the progress of human civilization modernization. The institutional attribute of collective fundamentally shapes the expansion path of modern urban civilization in China, and its form logic is specifically embedded in the interactive relationship between urban collectives and rural collectives. The collective external exclusivity makes the migration urbanization mode become the basic path for the further expansion of urban civilization in big cities.The compulsory distribution and external exclusivity of collective make the nearby urbanization model become the basic path for urban civilization to expand to county area. The cohesiveness of collective makes the local urbanization model become the basic path for urban civilization to expand to towns and villages.
