基于NEG方法的空间集聚实证研究的三个分支——希望有用

    One strand of literature examines whether production or exports tend to concentrate near large national or regional markets, as would be consistent with Krugman’s (1980) home-market
effect (Davis and Weinstein, 1999, 2003; Head and Reis, 2001; Hanson and Xiang, 2004).

    A second strand examines how technology diffuses across space and how this in turn
affects trade and industry location (Eaton and Kortum, 1999, 2002; Keller, 2002).

    A third  strand,  examines whether incomes are higher in  countries or regions with access to larger markets for their goods, as would be consistent with recent economic geography models (Hanson, 1996, 1997; Redding and Venables,2004; Head and Mayer)
