上犹社溪方言实词的兼类与活用

当语言中的一个新词诞生以后 ,只要表示与之相关的动作变化或状态的动词或形容词没有产生 ,就很可能直接用这个词来表示这种相关的动作变化或状态。因此 ,词的兼类是各种语言或方言、或各个不同时期的同一语言中常见的现象。在语言的发展史上 ,尽可能减少词的兼类现象 ,特别是通过形态变化等手段把兼类的词分化为不同的词 ,还有些词存在活用现象 ,显得很有地方特色。从此角度说 ,客家方言保留着较多的古语痕迹。     

零部件进口对中国制造业技术进步的影响

在中国制造业转型时期,零部件进口对促进我国技术进步至关重要,将出口品国内技术含量作为衡量技术进步的标准,对零部件进口与中国制造业技术进步的关系进行量化分析。研究结果表明:扩大零部件进口规模对技术进步有正向影响,但发挥作用存在一定时滞,且在高技术行业中促进作用尤为显著;扩大零部件进口种类能显著促进技术进步,主要体现在低技术行业;外商直接投资、人均资本和研发投入均对技术进步有正向影响,但对不同技术层次行业的影响程度存在差异。

Causal factor relations of supply chain competitiveness via fuzzy DEMATEL method for Thai automotive industry

Abstract

The automotive industry is complex and global. An automotive supply chain involves multiple manufacturers and service providers in different parts of the chain across different countries. Diffusion of the global production system creates both opportunities and challenges for the supply chain itself as well as production base countries. Thailand is a production base for over 15 automotive brands. The industry contributes significantly to the Thai economy and employs approximately half a million people. To address competitiveness of the Thai automotive industry, its supply chain is studied in this paper. Ten factors affecting the competitiveness of the Thai automotive supply chain are analysed through the fuzzy DEMATEL method. The method forms a structural model that categorises the causal or effect roles of the factors, and the degree at which they impact the supply chain. This study focuses on Tier 1 and Tier 2 manufacturers of the supply chain. The results reveal that there are three common causal factors and four common effects in both tiers. The other four factors play different roles in different tiers. Managerial implications relating to these factors are also discussed and certain recommendations proposed in order to enhance the competitiveness of the Thai automotive supply chain.     

How Sourcing of Interdependent Components Affects Quality in Automotive Supply Chains

In the automotive industry, many firms source key components from different suppliers, even though the components may function interdependently. In this study, we investigate how component level interdependence impacts quality performance and analyze how various operational factors moderate this relation. We synthesize information from several case studies to model the quality challenges faced by an automotive firm. For several sub‐assemblies that go into its products, the firm sourced key components from two different suppliers. The sub‐assemblies would fail whenever a component fails, but due to interdependent operations, failure of one component could cause the failure of the other. The firm found it challenging to improve the suppliers' quality performance as it was difficult to trace the failures to specific components. Our analysis reveals that – (i) the impact of interdependence is governed by the supply chain structure: reducing the interdependence between components improves quality when suppliers provide the components, but reducing interdependence worsens quality when the firm manufactures the entire sub‐assembly; and (ii) the relation between interdependence and quality performance is moderated by factors such as penalties, production costs, and interdependence costs. Additionally, we find that quality performance is lower when the firm outsources the components than when the firm manufactures the entire sub‐assembly. We identify coordinating mechanisms that leverage incentives and penalties to bridge the quality performance gap.     

长江下游安庆复式分汊河段整治关键部位研究

分汊型河道是冲积平原河流中的常见河型,分汊型河段与单一河段的最大不同是分汊型河段具有两汊或多汊过流,分流区和汇流区的水沙具有与单一河道不同的运动特点,并容易因分汊口门的放宽,水流分散,泥沙在此淤积造成水深不够,产生碍航问题。分汊河型又包括很多不同类型,其中对复式分汊型河段航道问题的研究较少,整治技术也不成熟。以长江安庆复式分汊河段为研究对象,采用河工模型试验研究与实测资料分析相结合的方法,在分析安庆河段水流运动规律的基础上,探讨了不同整治部位实施工程的效果,通过综合比较提出了安庆复式分汊河段的整治关键部位。
