I've actually read a bit also....

Couple of salient points :
As the sole governing party in the PRC, the CCP (Chinese Communist Party)
assumes an all-encompassing leadership role within the country. This
includes the ability to exercise control over the PRC’s economy via both state
owned enterprises (SOEs) and private enterprises. For example, Article 19 of
the 2018 revision of the Companies Law of the PRC states that not only must
PRC companies “establish CCP branches in companies to carry out activities
of the Chinese Communist Party” when required, but that they must “provide
necessary conditions to facilitate the activities of the Party.” The impact of this
can be seen in the fact that in 2021 over 92% of the top 500 companies in the
PRC hosted government party cells, with the expectation that this number will
rise to 100% given a change in governance requirements in 2018.
And..;
This influence is clearest in SOEs such as the Liugong Group, which is not
only entirely state-owned, but actively promotes its alignment with government
policy. However, the influence of the GoC also extends to the private sector.
For example, while the Sany Group is not an SOE, the TRA identified that
there was at least one leading PRC politician and a senior member of the
GoC either holding a director position or being a member of the board.
