随着全球变暖的趋势越发紧迫，节能减排成为我国当下经济发展的重要目标之一。赣江新区作为我国刚刚成立的国家级新区，其中的共青城市也被纳入全国低碳试点城市之列，如何借此契机发展低碳经济，将直接关系到赣江新区今后的可持续发展。本研究采用了Laspeyres指数分解法，选取了特定的效应指标，对赣江新区成立前后碳生产率的变化情况及各个指标对碳生产率的贡献情况进行了分析和研究，结果表明从整体上看，赣江新区的成立一定程度上促进了碳生产率的提高，但是从行业的角度来看不同行业对碳生产率的贡献差距较大，情况不容乐观。要实现赣江新区的低碳经济发展，必须树立绿色金融的观念；调整产业机构袁淘汰落后产能；合理分配有限的碳排放空间，提高自然资源的综合利用水平。

As global warming becomes more and more serious, energy conservation and emission reduction has become one of the important goals of China忆s current economic development. As the newly established national new district in China, the Ganjiang New District is also included in the national low-carbon cities. How to take this opportunity to develop a low-carbon economy will directly affect the future sustainable development of the Ganjiang New District. In this paper, the Laspeyres exponential decomposition method is adopted, and the specific effect indicators are selected. The changes of carbon productivity before and after the establishment of the Ganjiang New District and the contribution of each index to carbon productivity are analyzed and studied. The results show that the overall situation is that the establishment of the new district has promoted the improvement of carbon productivity to a certain extent, but from the perspective of the industry, the contribution of different industries to carbon
productivity are varied, and the situation is not optimistic. To realize the low-carbon economy development of the Ganjiang New District, we must establish the concept of green finance, adjust industrial institutions to eliminate backward production capacity, rationally allocate limited carbon emission space, and improve the comprehensive utilization level of natural resources.
