基于相关性分析的土地违法结构与经济结构变化关系探讨

土地违法结构与经济结构关系的研究是保障土地合法利用和经济健康发展的重要课题。通过运用典型多元相关分析与Pearson相关分析法，对1992年～2004年间的土地违法结构变化与经济结构变化进行相关性分析。研究结果表明，经济结构变化与土地违法结构变化是相关的；第一产业生产总值比重与其他违法用地比重呈负相关；建筑业产值比重与破坏耕地比重呈正相关，与其他违法用地比重呈显著正相关，与未经批准占地呈显著负相关；固定资产投资比重与非法批地比重呈负相关。研究结论揭示了土地违法结构变化与经济结构变化之间的确存在一种必然的相关关系。因此，根据经济结构与土地违法结构变化之间的相关关系，应密切注视经济发展中的土地违法结构变化，并制定长期策略，采取多样化措施，在减少土地违法总量同时，重点监控土地违法类型变化，合理确定一定时期应采取的主导调控措施。

Relation between Land Violation and Economic Structure Change based on Correlation Analysis

The research on the relation between land violation structure and economy structure is an important issue to ensure the legal utilization of land and the healthy development of economy. It is beneficial to know both the logic relation between them and the influence land exerts on economic development. We should be aware that the development of society and economy comes at a cost of land and the importance of regular land use. Employing the canonical multiple correlation analysis and the Pearson correlation analysis, we analyzed the changes between land violation structure and economic structure and the relations between them from 1999 to 2004 in China. The results show that: 1) the changes of land violation structure and economic structure are correlative; 2) proportion of primary industry is the negatively correlated to the proportion of other illegal land; 3) proportion of the production value of building industry is in direct ratio with the proportion of destroyed cultivated land, and has an obvious positive correlation with the proportion of other illegal land while it is in reverse ratio with the proportion of unauthorized land occupation; 4) the rate of investment in the fixed assets and the rate of illegal acts of grant are negatively correlated. The above conclusions reveal that there is a certain correlation between the changes of land violation structure and economic structure from 1999 to 2004 in China. The change of economic structure exerts a certain influence on land violation structure in China. Since it is closely related to the development of society and economy, the change of land violation structure would also affect the development of society and economy. In a word, according to the correlation between the changes of land violation structure and economy structure, we should pay close attention to the structure change of land violation, formulate a long-term development strategy and take diversified measures to reduce total amount of land violation, and establish reasonable leading regulation and controlling measures for certain periods.
