New and old driving force conversion is regarded as the principal strategy to realize economic development from high speed to high quality currently in China. Exploring the temporal-spatial evolution of the new and old driving force conversion can help decision-makers formulate relevant policies and regulations, thereby promoting industrial restructuring and sustainable development of the economy. From the view of regional evolution, this study first presents the methods of measuring conversion speed and direction of the new and old driving force, including the Moore index and the advanced industrial structure coefficient. Then, the conversion development of new and old driving force is evaluated using an improved entropy method and a novel evaluation index system with eight first-level and twenty-two second-level indicators. After that, the spatial correlation of new and old driving force conversion is further analyzed using the global and local Moran’s I, respectively. Finally, the proposed approach is applied to regional cities’ temporal-spatial evolution analysis in Shandong province in China. The results show that: (1) each cities’ conversion development of new and old driving force in the studied province has been steadily improved in recent years, and their conversion developments show noticeable agglomeration effects from a spatial view; (2) however, the conversion of the new and old driving force in the studied province is still at a low level with unbalanced and insufficient development, which prompts the urgent need to accelerate inter-regional collaboration according to their local conditions in the future.

Accompanied by the concept of supply-side structural reform and conversion of new and old driving energy to create a new round of economic development in China, cement supplier evaluation and selection are increasingly crucial for concrete production plants, ensuring not only raw material supply with high quality and at a reasonable price but also sustainable and long-term cooperation with suppliers. Given the limitations of the existing approaches, this study proposes a cement supplier evaluation and selection framework based on the combination of the improved FAHP-CRITIC method and VIKOR method. We first develop a cement supplier evaluation and selection index system under the background of new and old driving energy conversion, including eight first-level indicators and twenty-one second-level indicators. The proposed model then uses triangular fuzzy numbers AHP (TFN-AHP) and the improved CRITIC method to calculate subjective and objective weights by replacing the coefficient of variation with standard deviation, uses the ideal solution-based method to determine their combination weights, and combines the VIKOR method to calculate the comprehensive evaluation values of candidate cement suppliers. After that, the proposed approach is applied to evaluate and select ten cement suppliers for concrete production plants, and the results are compared and analyzed with those using the traditional method. The results of the comparison show that the proposed strategy can be scientific and reliable, helping managers to make the right decision under the background of new and old driving energy conversion in China.
