The role of infrastructure in macroeconomic growth theories
Investment in infrastructure is widely regarded as promoting economic growth. Moreover, infrastructure has a critical and often irreversible role in locking in patterns of development. Therefore, it is surprising that macroeconomic growth theories do not explicitly incorporate the notion of infrastructure systems. This lacuna is studied here, exploring the mechanisms via which infrastructure can impact an economy's growth rate and how these mechanisms may be represented in existing macroeconomic growth theories. We confirm the important role of transport and digital communications infrastructure in reducing the cost of trade, thereby facilitating economies of scale as well as knowledge accumulation. We also consider the limiting effect that inadequate infrastructure can have on economic growth. Some, but not all, economic functions of infrastructure can be represented in current macroeconomic models due to their inherently non-spatial nature: Romer models include knowledge accumulation and energy economic...
Construction conditions of functional region for grain production were investigated and construction achievements in Huzhou City since 2010 were summarized. There were many difficulties identified in this study: appropriate regions selection, fund raising, subject cultivation and follow-up management in the process of construction. According to the existing problems, some strategies were proposed,for example, to strengthen the leadership and cooperation among the government multi-branches, to integrate resource and increase investment from government, to perfect the mating facilities and improve service quality for the functional region, and to establish the innovative mechanism and strengthen the follow-up management.
