摘要

土地资源空间互动的发展加强了虚拟建设用地的流动,从而加剧了中国区域间贸易的不平等。人们对区域间的不平等程度知之甚少。本研究试图通过环境经济效益来估算区域间贸易不平等的程度。我们将城市层面的多区域投入产出模型与一种新的分类方法相结合,计算了城市间的虚拟建设用地流量,并分析了其对区域经济和碳平衡的影响。结果表明,发达地区是区域间贸易的主要受益者,这体现在土地利用效率上。中国经济中心逐步南移,区域间贸易不平等程度不断加剧。发达地区间虚拟服务业用地流量上升,而欠发达地区仍是原材料供应地,进一步加剧了地区间贸易的不平等。

Quantifying Inter-regional Trade Inequality of China's Cities Based on Environmental-economic Benefits in Virtual Built-up Land Flow

The development of spatial interactions of land resources enhances virtual built-up land flow, which contributes to China's inter-regional trade inequality. Little is known about the degree of inequality among regions. This work seeks to estimate the degree of interregional trade inequality through environmental-economic benefits. We combined a multiregional input–output model at the city level with a new classification to calculate the virtual built-up land flow among cities and analyzed its implications for the regional economy and carbon balance. The results indicate that developed regions were the main beneficiaries of inter-regional trade, as reflected in land-use efficiency. China's economic hub has been progressively shifting southward, and the inter-regional trade inequality has continuously increased. The flow of virtual service industry land among developed regions rose, while underdeveloped regions remained suppliers of raw materials, further increasing inter-regional trade inequality.
