Two-Stage Efficiency Structure Analysis Model of Shipbuilding Based on Driving Factors: The Case of Chinese Shipyard

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.

Joint duration-cost-quality optimization model for complex product supply chains under contingency conditions

“…The problem of complex products in the "main manufacturer-supplier" model has been studied by many scholars, focusing on two aspects: First, the research is carried out from the perspective of contract design based on game theory. Based on the evolutionary game, Xue et al [ 17 , 18 ] proposed a dynamic penalty mechanism that is more conducive to complex product quality control from the perspective of contract design, and designed a contractual game model of quality improvement incentive gain-sharing contracts between the main manufacturers and suppliers of large ships, taking into account supply chain synergy factors. Liu and Wu [ 19 ] designed a class of quality incentive contracts for complex product supply chains by considering the effects of short-term economic benefits and long-term quality reputation, and by constructing a "benefit-reputation" utility function for quality cooperators in the supply chain to achieve a win-win situation in terms of their overall utility.…”

Efficiency Decomposition Analysis of the Marine Ship Industry Chain Based on Three-Stage Super-Efficiency SBM Model—Evidence from Chinese A-Share-Listed Companies

“…Li, Zhang, and Liu (2017) [6] used stochastic frontier analysis to calculate the technical efficiency of the shipbuilding industry, and then further analyzed the regional development differences as well as the influencing factors of technical efficiency. Xue et al (2020) [20] constructed a two-stage internal production efficiency structure analysis model (ESAM) to analyze the efficiency of the internal operation, process, and management of Chinese shipyards.…”

Comparing the productivity of major shipyards in China, South Korea, and Japan – an application of a metafrontier framework

“…They observed that rules based on combinations of the time criticality index, resource criticality index and shortest processing time yield the most and the least efficient trade-off, respectively, between time and resource-oriented objectives. Xue et al (2020) indicated that building technique, resource ability and management level are the three major drivers of the production efficiency of shipbuilding. Based on an empirical study on one of the largest state-owned shipbuilding companies in China, they suggested that improving management Productivity of major shipyards efficiency and technique efficiency should be the main direction taken to improve Chinese shipbuilding efficiency.…”
