The incremental construction land differentiated management framework: the perspective of land quota trading in China

Construction land plays a vanguard role in China's rapid urbanization process. However, confront with massive loss of farmland resources, the highly centralized land-use planning and management system established by the central government in 1998 stipulates that the red line of 1.8 billion mu of farmland should be guarantee to ensure food security. A series of land management system innovations such as the replacement of basic farmland in different places, the compensated supplement of farmland in different places, and the land conversion quotas transregional transaction in Zhejiang province have received increasing attention, under the premise that neither dissipating the economic development efficiency nor breaking the constraints of various planning quotas. Inspired by the three-phase efficiency improvement based on the concept known as the adaptive efficiency, this article first proposes the inherent policy shortcomings as incalculability, inseparability, and uncontrollability. Then, adopting the mathematical model derivation and economic analysis tool, we demonstrate that the general allocation + competition allocation + rewarded allocation of new construction land quota allocation scheme has improved the three-stage Pareto efficiency. Relying on the network analysis of the cross-regional trading in Zhejiang province, the time hotspot, regional hotspot, Siphon effect, price fluctuation and inequality of opportunity are also observed in the process of trading. The authorities should play a quasi wedge-like blocking role in due course. It is therefore suggested that a differentiated management scheme should be adopted considering the variance in regional resource endowments and social ecosystem. This paper expected to shed light on improving construction land-use efficiency for China and other similarly placed developing countries.
