ABSTRACT: The purpose of this paper is to build an
efficiency evaluation model based on efficiency drivers. Building technique,
resource ability and management level are the three main driving factors in
production efficiency of shipbuilding. Two-stage internal production efficiency
structure analysis model (ESAM) firstly decomposes the shipbuilding system
efficiency into three dimensions of subsystem efficiency structures to express
the driving effect of the three driving factors of technique, operation and
management. Secondly, ESAM uses system efficiency function and dimension
structure efficiency function to express the relationships between the efficiency
of each level and its subordinate efficiency. The contribution of subsystems to
system efficiency is represented by the regression coefficient while the
driving relationship between the efficiency of the subsystems and the
efficiency of the system is expressed by the moving average trend curves of the
system efficiency and the structural efficiency of each dimension. The
empirical analysis shows that the case shipyard inner production is
inefficient, which implies that most Chinese shipyards may be in the same
condition, or even worse. It also shows that operation efficiency has the
greatest driving effect on shipbuilding system efficiency while the driving
effect of technique efficiency is not obvious, which means that improving
management efficiency and technique efficiency should be the main direction
taken to improve Chinese shipbuilding efficiency.
