*3.3. Spatial Autocorrelation of the CCD between FT and LM*

The global *Moran's I* index estimates of the CCD of FT and LM in China from 2015 to 2019 were all positive, demonstrating an overall positive spatial correlation. The significance test was passed by all *Moran's I* indexes during the study period, and a highly significant correlation was observed between 2015 and 2019 in *Moran's I* indexes. Some years' low global *Moran's I* indexes suggested that there was little clustering and no obvious spatial autocorrelation feature. Among them, the maximum value of 0.3678 was reached in 2015, followed by a cyclic development trend of decreasing firstly and then increasing and decreasing, which reached the minimum value of 0.1773 in 2019. Therefore, the CCD of FT and LM in China shows a development trend of agglomeration–dispersion over time (Figure 5).

Most provinces are located in H-H and L-L agglomeration areas, indicating that both provinces with higher coupling coordination of FT and LM and those with lower coupling coordination have emerged as agglomeration effects and showed a tablet distribution in space. Specifically, from 2015 to 2019, the number of H-H agglomeration areas increased from 8 to 11, and the proportion increased from 26.67% to 36.67%, with this type of area with the greatest proportion. The increase in the number of H-H agglomeration areas indicates that the development level of both FT and LM in China has entered a high level, and it has basically formed a benign coordination situation with mutual promotion (Table 4). In terms of spatial distribution, it gradually expands in scope, with the development trend from relatively scattered to concentrated, and the distribution range is concentrated in the central-eastern region. In general, the strong–strong clustering type is primarily distributed in the east-central region, and the weak–weak clustering type is primarily distributed in the western region. The spatial coordination of FT and LM in China has significant clustering characteristics and tends to be stable. The distribution and number of clustering types change slightly with time, but generally remain stable.
