The synergy of digitalization and greening (DGS) enhances the resilience of the industrial chain (ICR), a critical aspect for the sustainable growth of the national economy. This symbiotic relationship not only facilitates the enhancement of quality and efficiency within the manufacturing sector but also propels forward sustainable economic development. Therefore, how DGS can improve ICR deserves in-depth study. Drawing on the panel data encompassing manufacturing industries across 30 provincial-level administrative regions in China from 2013 to 2022, this study employs a regression model to delve into the mechanisms through which DGS within manufacturing industries impacts ICR. The main results are as follows: (1) DGS in manufacturing makes a positive contribution to ICR; (2) The impact of DGS on ICR varies across regions, with a diminishing effect from the eastern to the western region. (3) Technological innovation reinforces the influence of DGS on ICR. (4) Spatial measures show that the development of DGS in one location has a negative spatial spillover effect on ICR in neighboring areas. Based on the above conclusions, this paper puts forward a series of recommendations aimed at promoting industrial chain resilience.

With the goal of carbon peaking and neutrality, carbon productivity has become a means of sustainability in manufacturing, and the impact of the synergy of digitalization and servitization (DSS) on carbon productivity (CP) deserves in-depth study. Based on data with respect to manufacturing in 30 provinces in China from 2013 to 2020, a coupled coordination degree model is used to calculate the degree of manufacturing coordination. A regression effect model is used to explore the intrinsic mechanism of the impact of DSS on CP. The main results show the following: (1) The DSS in manufacturing positively contributes to enhancing CP, and there are non-linear features in both. (2) Technological innovation can contribute to the impact of DSS on CP, as does industry structure, and there is a mediating effect between the two. (3) When economic growth is used as the threshold, DSS and CP reflect a positive “U” relationship. Based on the above findings, policy recommendations are made to promote the sustainable development of manufacturing.
