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.
