求翻译：　　根据我们的研究，在英美等发达市场经济国家，房地产业中根本不存在我国这种基本上不做什么物质劳动和增值服务的房地产开发经营企业。房地产业由两类企业构成，一类是房地产生产建设企业，这是国际意义上的建筑生产企业。这类作为第二产业的企业如同我国的工业企业一样具有完备的房地产原料采购、营造和销售功能，是房地产的真正生产者和开发者。另一类是房地产服务业，由不动产抵押银行、房屋信托投资公司、不动产投资基金、房屋租赁经营、房屋中介代理、房屋开发创意策划、房地产价值评估、产权代理、物业管理、IT服务等行业构成的房地产服务业体系。这些房地产服务业根据服务对象的不同又可以分成为消费者服务的房地产服务业和为房屋生产者服务的房地产服务业两类。在英美发达国家，房地产开发企业都是建筑企业，建筑业由于其生产率上升快、收入弹性高、产业关联性强等特性，成为国民经济的最重要的支柱产业之一。这正是上世纪70年代末邓小平同志到欧美访问时所看到的现象，他后来提出了把建筑业作为我国国民经济支柱产业和推进住宅商品化的构想。是什么意思？
