Urban agglomerations are engines of economic growth. As such, sustainable economic growth demands sustainable urbanisation. There is evidence which indicates that higher the non-agricultural labour share, higher is the log of output per worker in the non-agricultural sector. However, this relationship is true for the agricultural sector as well. This implies how the growth of cities has a positive influence on national productivity. But this also implies that the benefits of economic growth driven by urbanisation get transmitted into the rural areas. This underscores the importance of cities in improving the agricultural productivity of a nation assuming that the channels, by which the above-mentioned transmission takes place, are intact.
