There is a growing body of literature that suggests that advanced economies are experiencing an economic restructuring such that the engines of economic development are smaller, more independent, firms acting in an increasingly cooperative manner. In assessing whether the UK economy is actually experiencing such a shift in inter-firm relations, the paper firstly assesses the existing evidence. This evidence suggests the continued dominance of large firms and only limited and uneven movements away from a low-trust system. Secondly, the paper presents evidence on the nature of inter-firm relations in the UK engineering construction industry in the 1980s and 1990s. the research shows considerable improvement in performance against schedule associated with the emergence of management contractors. Management contractors can improve performance either by adopting a high-trust route in which they seek to make overall efficiency gains by integrating design and construction, or by adopting a low-trust route in which they seek to reduce scope for opportunism by rigidifying design, and by passing on risk. Evidence is presented which shows that management contractors in the UK have so far predominantly adopted the low-trust route to improved performance. Cumulatively, the evidence suggests the dominance of the ‘top down’ control of inter-firm relations in the UK. 相似文献

ABSTRACTIn this paper a novel information model that can be used in Manufacturing Execution Systems is presented. The model is based on the fusion of ISA95, AML and OPC UA. ISA95 is used to define, unify and describe the details of a product and production technology. It also enables communication with ERP systems. The AML standard allows information about the production facilities to be presented. The OPC UA address space represents different parts of an information model while the OPC communication protocol enables it to be linked to actual production systems. The proposed concept is illustrated using an actual example of a production line for electronic devices. 相似文献

A two-sector growth model with endogenous technical change is presented. Concerning technical change, we assume that it is reflected by increases in the stock of human capital which are acquired through learning by doing. As a result, it turns out that transitory or, using the Hopf bifurcation theorem, persistent oscillations of the economic variables may be the outcome. Thus we are able to show that learning mechanisms alone may be sufficient to destroy the circular flow as described by Schumpeter. 相似文献

The nonperforming loans (NPLs) are co-generated by creating the profit in a bank, and this article build a joint production model to measure the reduction cost of nonperforming cost. By using a data set of China’s 13 commercial banks, the conclusions show that the reduction cost of NPLs is lower, which suggests that it is not a good choice for China’s commercial bank to hold the NPLs. 相似文献

This paper uses Census microdata to examine how starting a business as a franchise rather than an independent business affects its survival and growth prospects. We assess factors that influence the decision to become a franchisee and use various empirical approaches to correct for selection bias in our performance analyses. We find that franchised businesses on average exhibit higher survival rates than independent businesses; but importantly, the difference is small compared with claims in the trade press. The effect is also short lived: conditional on surviving a year or two, we no longer find survival (or growth) differences. We then explore two potential sources for this small survival advantage, namely franchisors’ screening process and the benefits arising from the brand and business know‐how provided by franchisors. We find evidence that both of the sources contribute to the franchising advantage. 相似文献

Since 1990 the telecommunication sector in Poland has been undergoing rapid development and modernization. It is heavily dominated by Telekommunikacja Polska SA (TP SA), a state-owned company which is split into 10 regional directorates. Although TP SA enjoys a legal monopoly only over international traffic, it is a de facto monopolist in the Polish market too. Apart from difficulties in funding local telephone operations, many of the difficulties facing private competitors to TP SA focus on interconnection and pricing issues. The Anti-monopoly Office, which seeks to restrict unfair competition and restrictive business practices, has been monitoring the compliance of TP SA with the statutory standards. In its business practices TP SA has been reluctant to meet the required standards, particularly these relating to the setting of tariffs. This has been found to have a restrictive effect on the emergence of competition in the form of local operators. 相似文献

Total Factor Productivity, the East Asian Miracle, and the World Production Frontier. — The post WWII growth of the East Asian Tiger states has stimulated the discussion about its determinants. Young and Krugman hold that high capital accumulation rather than gains in efficiency or technological progress has spurred growth. Nelson and Pack, however, have recently criticized the methods of measuring technological progress. Applying the nonparametric approach to frontier production function determination and the Malmquist index of total factor productivity change, the authors take up this criticism. They calculate productivity indicators for a sample of 18 American, Asian, and European countries. For the Tiger states, their results confirm that capital accumulation was the main source of growth in 1960-1973, whereas they find evidence for an increasing importance of efficiency improvements for the growth in 1973-1990. 相似文献

We present work concerning the formal specification of business processes. It is of substantial benefit to be able to pin down the meaning of business processes precisely. This is an end in itself,
but we are also concerned to do so in order that we might prove properties about the business processes that are being specified.
It is a notable characteristic of most languages for representing business processes that they lack a robust semantics, and
a notable characteristic of most commercial Business Process Management products that they have no support for verification
of business process models. We define a high-level meta-model, called
Liesbet
, for representing business processes. The ontological commitments for
Liesbet
are sourced from the YAWL workflow patterns, which have been defined from studies into the behavioural nature of business
processes. A formal characterisation of
Liesbet
is provided using Milner’s Calculus of Communicating Systems (CCS). In this article, we omit some of the technical details
of this characterisation and instead present the essential features by means of an abstract machine language, called LCCS.
We also explain how we have facilitated the verification of certain properties of business processes specified in
Liesbet
, and discuss how
Liesbet
supports the YAWL workflow patterns. We include a simple three-part example of using
Liesbet
. 相似文献
