江西省水资源利用与产业结构关系研究

Relationship between Water Resource Utilization and Industrial Structure in Jiangxi Province

随着国家水资源刚性约束制度提出,产业发展面临水资源红线硬约束。为提升水资源利用效率,促进水资源与产业协调发展,采用考虑非期望产出超效率SBM模型和全局ML指数测度了2011—2020年江西省水资源利用效率及其动态变化,利用泰尔指数等分析产业结构及布局变化,并借助灰色关联法评价了用水量和用水效率与三次产业发展的关系。研究发现:水资源利用与产业结构具有较强相关性,两者关系存在明显的区域分异特征。江西省用水效率与产业结构的关联度总体略高于用水量,第一产业与水资源利用关联度最高,二、三产业次之,各设区市亦存在区域分异;用水效率总体不断提高,产业向高级化方向发展,但存在区域不均衡不协调等问题。最后提出了采取差异化考核等建议。

With the introduction of the national rigid constraint system for water resources,industrial development is facing hard constraints from the red line of water resources.To improve the efficiency of water resource utilization and promote the coordinated development of water resources and industries,this paper uses the SBM model considering unexpected output super efficiency and the global ML index to measure the water resource utilization efficiency and its dynamic changes in Jiangxi Province from 2011 to 2020.The Thiel index and other indicators are adopted to analyze industrial structure and layout changes,and the grey correlation method is applied to evaluate the relationship of water consumption and water use efficiency with the development of three industries.Research has found that there is a strong correlation between water resource utilization and industrial structure,and there is a clear regional differentiation characteristic in the relationship between them.The overall correlation between water use efficiency and industrial structure in Jiangxi Province is slightly higher than that of water consumption.The primary industry has the highest correlation with water resource utilization,followed by the secondary and tertiary industries,and regional differences also exist in each city.The overall efficiency of water use continues to improve,and the industry is developing towards higher levels.However,there are problems such as regional imbalance and coordination.Finally,suggestions such as differentiated assessment are proposed.
