| The development zone not only allocates economic resources in an efficient way which promotes economic development, but also provides a great amount of experience for intensive land use. Throughout 30 years'reform and development, the social-economic development has stepped in the new era in China. In the surroundings, the development zone is considered as the mode with Chinese institutional background, and this mode can efficiently harmonizes the incompatible relationships among scarce economic resources, rational city expansion and intensive land use. However, some development zones in China have such problems of land use as land resources waste, low efficiency of land use, land eco-system deterioration and unfair land use rights. The Lanzhou high-tech development zone built 20 years ago has developed the successful mode of project construction and land use in Gansu Province, and contributed a lot to regional economic development in Lanzhou City. Whereas it is ambiguous whether the Lanzhou high-tech development zone has the same problems of land use, and in particular, whether the land use is intensive in the development zone.Therefore, the paper employs the Lanzhou high-tech development zone as a case to explore the problems of land use in development zones, analyze the reasons for the problems, and indentify some measures promoting the intensive land use in the Lanzhou high-tech development zone. The contribution of the paper is to give some guidance and implication for the land use management in development zones. The study procedures are as follows:(1) the status of land development in the Lanzhou high-tech development zone is surveyed; (2) the scientific evaluation system of intensive degree of land use in development zones is established based on analyzing the status of land development, and then the evaluation of intensive degree of land use in the Lanzhou high-tech development zone is conducted; (3) the paper assesses the intensive land use potential of the Lanzhou high-tech development zone followed by the evaluation of intensive degree of land use; (4) some useful policy measures of promoting intensive degree of land use in the Lanzhou high-tech development zone is put forward with based on investigating the successful modes and measures employed in the economic-developed development zones. The research conclusions arrive at as follows:(1) the intensive degree of land use in the Lanzhou high-tech development zone stays at relatively high level, and the intensive land use potential is moderate; (2) the land use supervision system performs well; (3) the imperfect land supply market is thought of as one of the main obstacles of promoting intensive degree of land use; (4) the Lanzhou high-tech development zone is confronted with extremely high land supply pressure in the future.Based on the above research results, the policy implication is as follows:(1) enhancing land supply by reusing the stock land; expanding spatial dimension to increase available land area; (3) transforming from attracting investments to selecting investments; (4) innovating the system arrangements corresponding intensive land use; (5) improving land supply market to enhance land allocation efficiency. |
