Abstract: Secondment is a flexible employment system used by local governments in China to cope with personnel constraints， reflecting the tacit agreement and consensus formed by superiors and subordinates to achieve governance goals and accomplish governance tasks. Based on the theoretical framework of governance-oriented collaboration， the types of secondment and its generative logic are analyzed， and secondment is viewed as a positively oriented superior-subordinate and organization-individual collaboration strategy that takes governance achievement as the goal. There are four types of grassroots civil servants' secondment in China: pressure transmission-authority obedience， resource supply-opportunity competition， task orientation-responsibility fulfillment， and strong mobilization-rational compliance. In terms of generative logic， grassroots civil servants' secondment is the result of a multifaceted strategy of institutional flexibility-resource embedding-individual choice mobilized by the goal of governance. Institutional flexibility explains the possibility of grassroots civil servants' secondment from the institutional level， and points out that secondment is the flexible room of the personnel system left by the local governments to deal with governance uncertainty. Resource embedding analyzes how to promote the process of grassroots civil servants' secondment at the organizational level， suggesting that secondment is an informal allocation process of human resources within the bureaucratic system facilitated by the superior departments based on power and opportunity resources. Individual choice focuses on the micro-action logic of the seconded grassroots civil servants， pointing out that whether an individual agrees to the secondment is a rational choice based on the consideration of institutional compliance and resource acquisition.
