在中国,城乡居民点用地有规范的人均指标,招标拍卖已成为获取经营性用地的主要方式,交通和水利设施用地主要受政府和区域重大政策影响,而工业用地既缺乏相应的用地标准,土地获取的市场透明度又不够。因此,如何提高工业用地效率是土地规划和管理的重要内容。已有的研究多采用指标体系的综合评价方法来评价土地集约利用程度,但缺少经济学原理,应用于具体的规划编制、管理和实施的局限性较大。结合中国福建省案例,提出全要素生产率方法来分析和度量之,既能测算土地集约度,也能说明要素的利用效率,具有简单可操作的优势。文中不知劳动所得比重值情况下的用地效率和集约评价方法也是有效可行的,虽不能排列出要素利用效率的顺序,但可同时给出资本与劳动的投入结构以及对它们利用的效率在各个地区之间的差异情况。案例研究还表明,福建其他地区随着与厦门和福州距离的增加,其投入和产出总的趋势在下降。福州与厦门可与杜能孤立国中的城市类比,而其他地区类似于孤立国中的郊区。因此要考虑土地区位对集约度的影响,但找出其参考点是关键。
In China, there are standard per capita indicators for the land used for urban and rural settlements. Tender auction has been the major access to the acquirement of operating sites. Land used for transport facilities and water conservancy facilities is mainly influenced by important governmental and regional policies. However, there are neither corresponding standards for industrial land nor adequate mark transparency for its procurement. Therefore, how to improve the efficiency of industrial land use is of prime importance for land use planning and governance. We found that most of the existing research papers introduce a weighted indicator to evaluate land intensive use, without the guidance of economic principles. The exiting method cannot be well applied for the compilation of land use planning and the process of management and implementation. We propose a means named total factor productivity, simple and practical, to evaluate the economic efficiency of industrial land use and compare the effects of intensive use in different cities of Fujian province in China. Also, a variant TPF method is feasible in the absence of labor incomes ratio. It is unable to arrange the order of factor use efficiency, but it could indicate the input structures of capital and labor and regional differences of their use efficiencies. Furthermore, the case study shows that the longer distance from Xiamen and Fuzhou, the lower inputs and outputs the other cities of Fujian province have. It seems that Xiamen and Fuzhou analogize the city in Thunen's isolate country while other cities like the suburbs in the book. Therefore it is necessary to consider the impacts of location on land intensive use, and finding the reference atlas is the crux.
