"Dr. Zhao poses the provocative question of how the
geographical distribution of economic activity
contributes to the aggregate growth of an economy.
With an analysis that considers both time and space
he examines the relationships between growth, the
geographic distribution of growth and the
distribution of inputs that contribute to growth.
His analysis shows that productivity and earnings
follow or lag "behind" the geographic distribution
of employment both temporally and geographically.
Further, he shows that the U.S. economy demonstrates
a remarkable increase in both geographic scope and
spatial intensity. The analysis is dynamic, the
results convincing and provides one of the most
significant analyses of the relationship between
resource inputs and economic growth in a geographic
context to date. It is a convincing temporally and
spatially integrated and thus dynamic investigation
that deserves consideration by the broad communities
of economic geography, rural and urban planning and
