不用算,直接就有数据,直接房产投资和交易占3—5%,别的12-13%是租金,水电, 和业主自住型住宅的估算租金(这个是最大头)。
“Housing’s combined contribution to GDP generally averages 15-18%, and occurs in two basic ways:
Residential investment (averaging roughly 3-5% of GDP), which includes construction of new single-family and multifamily structures, residential remodeling, production of manufactured homes, and brokers’ fees.
Consumption spending on housing services (averaging roughly 12-13% of GDP), which includes gross rents and utilities paid by renters, as well as owners’ imputed rents and utility payments.”- source:The National Association of Home Builders of the United States.
