This study aims to systematically reveal the micro-level changes in water conservancy construction investment patterns in Jiangxi Province

and optimize the strategic investment planning for the next phase. Based on statistical data from the 13 th Five-Year Plan period

the study analyzes investment scale

funding sources

regional distribution

and project types across 4 dimensions. Using the coefficient of variation( CV) as a key analytical metric

it examines investment from 3 perspectives

such as total investment amount

proportional distribution of funds

and phased evolution. This study identifies fluctuations in investment levels in Jiangxi's water conservancy sector over the past 9 years and investigates the underlying characteristics. The findings reveal significant regional disparities and periodic fluctuations in investment. Investment remained stable during the 13 th Five-Year Plan period but accelerated during the 14 th Five-Year Plan period. Stable capital investment from central and provincial governments have effectively catalyzed synergistic growth in investment from municipal and county-level finances

bank loans

and private capital. While continuing to strengthen investment in key areas such as flood control

water supply

and irrigation

attention must also be directed to weak links in project preparation

power generation projects

and institutional capacity building

in order to optimize investment structure and improve overall efficiency. It is recommended that

during the 15 th Five-Year Plan period

cross-regional coordination and resource allocation be further enhanced to achieve more balanced and efficient water conservancy construction funding

thereby supporting the coordinated development of regional economies and societies.
