| Abstract: |
| We use the tenporal and spatial series data from 1985—2008 and apply trend analysis, co-integration, Granger causality analysis and location entropy evaluation to analyze the relationship between the arable land, the orchard number and the economic development of Changwu County. Through the ADF test, we get the long-term equilibrium model and the short-tern dynamical balance relationshipt of the available space of fruit industry and economic develop-ment. As the arable land per capita is in non-stable sequence, Granger causality test can explore the relationship between the arable land and the economic development. The results show that the county’s economic development is not at the ex-pense of arable land and the economic development has little effect on the cultivated area. The method of location entropy evaluation can be introduced to investigating the relationship between the development of fruit industry and the reduction of arable land in Changwu from the perspective of space. The results of location entropy evaluation demonstrate that the coordination ol development of fruits industry is different from that of the cultivated area while space diversity exists. |
