将以下内容翻译为英文：2021年A市委组织部先后任命证监会某高级官员及A市某副厅级干部担任国企总裁和董事长原总裁、董事长均不再担任公司核心管理人员此举引发各界对国企由市场竞争机制转向政治关联机制发展的猜测。

In 2021, the Organization Department of the A Municipal Committee successively appointed a senior official of the China Securities Regulatory Commission and a deputy department-level cadre of A City as the president and chairman of a state-owned enterprise, respectively. The former president and chairman no longer serve as core management personnel of the company. This move has sparked speculation from all walks of life about the development of state-owned enterprises shifting from market competition mechanisms to political affiliation mechanisms.
