基于裂区设计的城乡建设用地市场整合与异质性分析——以佛山市南海区为例OA

To test whether the collective construction land market and the state-owned construction land market in Nanhai District of Foshan City,the leading demonstration area of rural collective operational construction land,are integrated at different stages,this study collected a total of 3 127 urban and rural construction land transaction data samples(2010-2022)from seven townships(streets)in Nanhai District of Foshan City,and used the three-factor split-plot design to carry out statistical modeling and difference significance test to explore the impact of different land ownership,land use and spatial location on the market price of urban and rural construction land;Two-factor split-plot design is adopted simultaneously to analyze the independent effect and interactive influence of land use and location factors on the price of state-owned/collective construction land.The study found that(1)in the bottom-up local system exploration stage(2010-2015),there was no significant difference in the market price of collective and state-owned construction land(P＞0.05),indicating that,from the perspective of land price to measure the urban and rural construction land market,the urban and rural unified construction land market in Nanhai District has basically formed an integration in the bottom-up local system exploration stage.(2)Location(Township Street)factors have a significant impact on the price of collective and state-owned commercial land and collective industrial land,but have no significant impact on the price of state-owned industrial land.There is heterogeneity in how land prices across different ownership types and uses respond to location factors.(3)In the top-down central system reform stage(2016-2022),the prices of collective land for commercial use and state-owned land for commercial use converge,while the prices of collective industrial land and state-owned industrial land differ.This indicates that after the top-down central pilot reform policy allows collective construction land to enter the market,the prices of collective land for commercial use and state-owned land for commercial use tend to converge.In contrast,the prices of collective industrial land and state-owned land for industrial use differ through market mechanism adjustments,and the price formation mechanism converges.The synergistic effects of land ownership,use,and location on the prices of urban and rural construction land reflect the joint influence of property rights,use,and location on market prices.The essence of unification lies in the coordinated effects of market-oriented system reforms,land supply,and demand on the price formation mechanism.The research shows that introducing a split-plot design in the study of the land market economy,for statistical modeling and difference-significance tests,can effectively reveal the differential mechanism of urban and rural construction land price formation.This method is highly feasible and effective for deconstructing the multidimensional driving factors of land price differences and provides a new paradigm for the empirical study of land market economics.
