establishment of a corporate governance mechanism
with statutory powers and responsibilities,
transparent powers and responsibilities, coordinated
operation, and efficient checks and balances."
3.2 The Group Management and
Control System
Firstly, the essence of group management and control
is a set of management methods and institutional
arrangements established by the enterprise group
based on the property connection between parent and
subsidiary companies. By implementing management
control and resource coordination and allocation for
subordinate enterprises or departments, resources can
be effectively deployed in a wider range to achieve
efficient utilization and strategic coordination. The
group control mode determines the allocation of core
resources such as people and property.
Secondly, the group management and control
system is the key to efficient operation of enterprise
group. Influenced by enterprise attributes and
resource endowments, the management and control
mode selection, organizational structure and
responsibility design of the enterprise group need to
comprehensively consider the positioning of the
group headquarters and the governance and
management capabilities of its subsidiaries.
Generally, it can be divided into indirect control
relationship and direct control relationship. The
indirect control relationship refers to that the parent
company mainly controls the operating activities of
the subsidiary through the board of directors of the
subsidiary, and the control of the parent company is
only reflected at the level of the board of directors.
Direct control refers to that the members of the board
of directors of the subsidiary are all executive
directors from the parent company, and the parent
company's board of directors directly nominates the
senior management of the subsidiary, which can
directly affect the operation and management of the
subsidiary.
3.3 The Operation Management
System
Firstly, in a narrow sense, enterprise operation
management refers to the general term for the
planning, organization, implementation and control
of business activities such as product or business
supply, research, production and marketing. It is a
command and coordination management system that
runs through all systems of enterprise business
creation. In a broad sense, enterprise operation
management is a management activity that focuses on
the whole process of enterprise business value
creation, takes the enterprise business value chain as
the center, strategic planning as the starting point,
planning management as the leader, and performance
incentive as the core, systematically drives the
management of all links and functions of the
enterprise value chain, and ensures the coordinated
operation of all kinds of resources and functions, so
as to maximize the operating efficiency of the
enterprise and continuously improve the working
efficiency. The overall enterprise operation
management system can include strategic
management, business management, functional
management, digital management, corporate culture
management, etc.
Secondly, the operation management system is
relatively independent, but it is directly affected by
the group's control system and business attributes.
Under diverse corporate governance systems and
group management and control systems, there are
significant differences in the vertical design and
functional soundness of the operation management
system. Generally, for subsidiaries with mature
products, complete systems, efficient management
and single shareholder, more emphasis is placed on
centralized, institutionalized and standardized group
management and control mode. For subsidiaries with
more product innovation, low management
standardization and multiple shareholders, more
authorization and on-site decision-making authority
are required. The parent company participates in
corporate governance as a shareholder.
On the basis of Mintzberg's prototype of
enterprise organizational structure and Porter's
concept of enterprise value chain activities , this
research explores and constructs the basic model of
modern governance system of power grid enterprises,
