过渡期产业群的演化与政策启示——以浙江永康五金产业群为例 总被引:1,自引:0,他引:1
当前我国产业集群正处于过渡时期,市场机制的完善提高了市场交易主体间扩展信任水平,从而降低基于扩展信任的交易费用水平。随着集群规模不断扩大,理性的企业会选择更多地与传统集群外有竞争力的企业进行交易,从导致产业集群由以血缘与亲缘等为纽带的传统集群向基于扩展信任的现代集群演进。本文以浙江永康五金产业群为例对此进行了分析,提出了产业集群发展的几点方略。 相似文献

中国通货膨胀的福利成本研究 总被引:15,自引:1,他引:14
通货膨胀一直以来都是衡量一国宏观经济运行是否稳定和健康的重要指标。本文对国内外关于通货膨胀福利成本的研究发展进行了较为完整的综述,并在此基础之上运用消费者剩余方法和新古典宏观经济学一般均衡模型对中国通货膨胀的福利成本进行了计算和比较。实证结果说明,在中国高通货膨胀会带来较高的福利损失,因此将通胀率保持在较低的水平对提高中国的经济福利水平是有利的。 相似文献

AbstractBackground:To evaluate the cost burden of patients with advanced Parkinson’s disease (PD) according to the waking hours per day spent in OFF state. An analysis of resource use comprising medical services, professional care and informal care data from an observational, cross-sectional study was conducted.Methods:A total of 60 physicians comprising 40 neurologists and 20 geriatricians across the UK participating in the Adelphi PD Disease Specific Programme took part. There were 302 PD patients at H&Y stages 3–5. Patients were characterised according to the percentage of time per day spent in OFF state (<25%, 26–50%, 51–75%, >75%).Results:Average 12-monthly total costs increased according to the time spent in OFF state from £25,630 in patients spending less than 25% of their waking hours in OFF to £62,147 for patients spending more than 75% of their time in OFF. Overall, 7% of costs were attributed to direct medical care, while 93% were split between direct non-medical professional care (50%) and indirect informal care (43%).Limitations:Low patient numbers in the more advanced disease stages of PD led to very little or no data to directly inform some of the severe health states of the analysis. Data gaps were filled in with data derived from a regression analysis which may affect the robustness of the analysis.Conclusion:This study illustrates the increasing costs of advancing PD, in particular related to the time spent in OFF state, and identifies that the foremost cost burden is associated with the care needs of the patient rather than medical services. 相似文献

AbstractObjective:To compare the cost-utility of exenatide once weekly (EQW) and insulin glargine in patients with type 2 diabetes in the United Kingdom (UK).Research design and methods:The IMS CORE Diabetes Model was used to project clinical and economic outcomes for patients with type 2 diabetes treated with EQW or insulin glargine. Treatment effects and patient baseline characteristics (mean age: 58 years, mean glycohaemoglobin: 8.3%) were taken from the DURATION-3 study. Unit costs and health state utility values were derived from published sources. As the price of EQW is not yet known, the prices of two currently available glucagon-like peptide-1 products were used as benchmarks. To reflect diabetes progression, patients started on EQW switched to insulin glargine after 5 years. The analysis was conducted from the perspective of the UK National Health Service over a time horizon of 50 years with costs and outcomes discounted at 3.5%. Sensitivity analyses explored the impact of changes in input data and assumptions and investigated the cost utility of EQW in specific body mass index (BMI) subgroups.Main outcome measures:Incremental cost-effectiveness ratio (ICER) for EQW compared with insulin glargine.Results:At a price equivalent to liraglutide 1.2?mg, EQW was more effective and more costly than insulin glargine, with a base case ICER of £10,597 per quality-adjusted life-year (QALY) gained. EQW was associated with an increased time to development of any diabetes-related complication of 0.21 years, compared with insulin glargine. Three BMI subgroups investigated (<30, 30–35 and >35?kg/m2) reported ICERs for EQW compared with insulin glargine ranging from £9425 to £12,956 per QALY gained.Conclusions:At the prices investigated, the cost per QALY gained for EQW when compared with insulin glargine in type 2 diabetes in the UK setting, was within the range normally considered cost effective by NICE. Cost effectiveness in practice will depend on the final price of EQW and the extent to which benefits observed in short-term randomised trials are replicated in long-term use. 相似文献

This research examines cost engineering and costing in a British shipbuilding firm in the late nineteenth – early twentieth century. The firm maintained separate systems of contract accounting, costing and reporting for directors and employed internal data from these systems in performance measurement, the development of managerial incentives and the enforcement of managerial accountability. An apparent gap in the information required to manage the firm in a cyclical and highly competitive industry during a period of rapid organisational and technological change was filled by an informal and personal cost engineering system developed by the shipbuilding manager. The shipbuilding manager's cost engineering system employed a wide range of both internal and external data for use in cost management and in cost estimation, pricing and tendering. Thus cost engineering and costing developed to serve different purposes and developed in different spheres and along different trajectories. 相似文献

The risk of non‐indigenous plant pests entering the UK via international trade in fresh produce is increasing. The objective of this article is to identify existing and emerging supply sources for UK fresh produce importers and examine the extent to which they could provide invasion pathways. We tested the hypothesis that increased imports of fresh produce from new sources outside the European Union could increase the risks of non‐indigenous insect pests. We use a bio‐economic model approach in which the number of species arrivals is a function of the volume of imports, whereas the volume of imports itself is a function of gross domestic product, relative import prices and seasonality. The study has identified clear trends, which show import volumes of fresh produce and species detections increasing from new supply sources. If this trend continues in the future, then the UK inspection agency should expect to confront species from new suppliers in much greater numbers, given that import volumes of fresh produce are income elastic. 相似文献
