【摘要】：當前土地資源利用效率不盡理想,對其效率評價亦不能很好地揭示土地生態(tài)系統的內部特征。故基于系統理論視角,將中國土地資源生態(tài)系統解構為三個子系統:經濟子系統、社會子系統和環(huán)境子系統。在此基礎上,構建基于矩陣型結構的網絡DEA模型,對2006—2013年中國各省市土地資源生態(tài)利用狀況進行效率評估,并進行收斂性檢驗和影響因素分析。研究發(fā)現:當前,中國土地資源生態(tài)效率處于較低水平且呈現出總體下降的趨勢,環(huán)境子系統效率低下是制約土地生態(tài)效率提升的瓶頸;土地資源生態(tài)效率和社會子系統效率具有收斂趨勢,經濟子系統呈現發(fā)散態(tài)勢,環(huán)境子系統較為穩(wěn)定;土地資源生態(tài)效率與城鎮(zhèn)化水平、人均綠地和市場化進程呈正相關關系,與經濟規(guī)模呈負相關關系,區(qū)位因素影響明顯,土地執(zhí)法水平影響不顯著。結合實證結果,提出了相應的政策建議。
[Abstract]:At present, the efficiency of land resources utilization is not ideal, and the evaluation of its efficiency can not reveal the internal characteristics of land ecosystem. Therefore, based on the view of system theory, the land resources ecosystem of China is divided into three subsystems: economic subsystem, social subsystem and environmental subsystem. On this basis, the network DEA model based on matrix structure is constructed to evaluate the efficiency of ecological utilization of land resources in various provinces and cities of China from 2006 to 2013, and the convergence test and the analysis of influencing factors are carried out. The results show that: at present, the ecological efficiency of land resources in China is in a low level and showing a general downward trend, and the low efficiency of the environmental subsystem is the bottleneck restricting the improvement of the land ecological efficiency; The ecological efficiency of land resources and the efficiency of social subsystem are convergent, the economic subsystem is divergent, and the environmental subsystem is relatively stable. The ecological efficiency of land resources has a positive correlation with urbanization level, green space per capita and market-oriented process, and a negative correlation with economic scale. The influence of location factors is obvious, but the level of land law enforcement is not significant. Combined with the empirical results, the corresponding policy recommendations are put forward.
