以往传统的仅依靠现货市场运营的单一运作模式是新疆棉产业历年难以走出困境的主要症结所在。如何利用棉花期货助推新疆棉产业转变发展方式,实现优势资源转换,是新疆棉产业亟待解决的重大问题。本文阐释了棉花期货助推新疆棉产业发展的作用,分析了2号棉(新疆棉)合约缺失、新疆棉花指定交割仓库缺位等制约新疆棉产业有效利用棉花期货的因素,提出了新疆棉产业利用棉花期货转变发展方式的组织模式及对策建议。 相似文献

This article studies the integration of China's cotton market with the international market, especially the U.S. market. Investigating the futures prices from the Intercontinental Exchange (ICE) in the U.S. and the Zhengzhou Commodity Exchange (ZCE) in China with several time series models, we find that a long‐run cointegration relationship exists between these two series. The two markets share price transmissions, and based on results from an Autoregressive Conditional Heteroskedasticity (ARCH) model, we find their price volatilities are similar. We argue that China's recent exchange rate reform and its gradual liberalization in bilateral cotton trade since it joined World Trade Organization have had important impacts on these futures markets. Based on these findings, several important economic and policy implications are derived. 相似文献

改革开放以来,中国棉花生产重心呈现出由南向北,再由北向西北地区变迁的特点。新疆自1997年以来一直是中国最大的植棉省,2017年其棉花播种面积占全国总量的69.41%。本文从自然因素和政策干预两个视角分析其对棉花生产布局的影响。基于1978—2017年省级面板数据和多元线性回归模型分析发现:在全国层面,生长季平均日照时长和生长季平均降水量对棉花生产集中度有显著影响。生长季平均日照时长每增加10小时,棉花生产规模指数将大约上升0.354%;生长季平均降水量每增加1毫米,棉花生产规模指数将大约下降0.010%。增加新疆地区虚拟变量与气候变量的交叉项后,结果显示生长季平均温度对棉花生产规模指数有正向影响,相比其他地区,新疆的生长季平均温度每增加1摄氏度,棉花生产规模指数将大约上升9.629%,这可能与温度升高导致新疆积雪融化、地下水增加、宜棉范围扩大以及棉花生长期延长有关;生长季平均日照时长每增加10小时,棉花指数将大约上升0.359%。此结果基本验证了棉花喜光照、惧严寒的生长习性和新疆独特的自然优势。此外,不同时期制定的棉花政策也促进了棉花生产向新疆集中。结论表明自然和政策因素都对中国棉花布局向新疆集中具有重大影响。中国政府对新疆棉花发展的支持政策遵循了自然规律,发挥了新疆的自然条件优势。 相似文献

The effects of rising labour costs on global supply chains: the case of China’s cotton yarn industry
Rapid economic growth in China and India has resulted in rapidly rising labour costs in those countries. In this study a Muth-type model is used to assess the potential effects of this development on global supply chains using China’s cotton yarn industry as a case study. The model considers i) product differentiation at the yarn level; ii) imperfect competition in the markets for cotton yarn and raw cotton fibre, iii) input substitution between raw cotton fibre, labour, and capital; and iv) offsetting increases in the demand for cotton yarn caused by rising consumer income. Results suggest the effects of rising labour costs on the supply chain are modest, and easily swamped or obscured by the effects of rising income. Increases in industry market power (both oligopoly and oligopsony) have the same effect on the supply chain as increases in labour costs, raising prices to consumers of cotton yarn, and lowering prices to input suppliers, including foreign suppliers of raw cotton fibre. The combined effects of increases in labour costs and income have increased the factor shares for labour and to a lesser extent capital at the expense of raw cotton fibre. 相似文献

Abstract Many countries as they reduce price controls develop an interest in futures markets as a way to manage risk. This article explores the potential of using existing futures markets to hedge cotton in Turkey. Futures prices in New York and Liverpool are not cointegrated and only weakly correlated with cash prices in Izmir. Thus, existing futures markets have limited ability to reduce the risk faced by the cotton industry in Turkey. While there are obstacles to overcome, there does appear to be a potential demand for a cotton futures market in Turkey. 相似文献

Accurate modeling of skewness is needed to increase the actuarial fairness of crop insurance. We test Day's conjecture that crop yield skewness becomes negative as nitrogen rates increase and determine how well a linear response stochastic plateau (LRSP) production function matches the pattern of observed skewness using four long‐term nitrogen experiments. Stillwater wheat is consistent with Day's conjecture, but the skewness for Lahoma and Altus wheat yields as well as Altus cotton yields are not. The LRSP assumes normal random effects and can explain only a small part of observed skewness, so a new LRSP with skew‐normal random effects is introduced, which comes closer to explaining the observed skewness and should increase the accuracy of nitrogen rate recommendations. Negative skewness reduced optimal nitrogen rates and positive skewness increased optimal nitrogen rates. 相似文献

开放条件下中国棉花安全状况评估 总被引:1,自引:0,他引:1
棉花作为一个关系国计民生的重要商品,在我国国民经济中有着重要地位,然而,近年来棉花出现的一系列问题已引起社会的高度关注。本文尝试构建一套评价棉花安全的指标体系,并用之评估我国棉花安全状况。研究结果表明,总体说来我国棉花安全水平较低,且呈下降趋势。这需要引起我们的高度重视。 相似文献

我国棉花产业安全的表现、原因及传导机制 总被引:1,自引:0,他引:1
棉花的大量进口、国内棉花生产的不稳定性及其所表现出的国际竞争力较弱等特征严重威胁到我国棉花产业的安全。通过对我国棉花产业的适应性、抗压性和产业发展潜力与成熟度等具体表现的分析,从市场机制、生产条件及政策因素等方面阐述了其对我国棉花产业安全的影响途径与传导机制,并通过实证分析得出:生产方式水平低下、市场调控能力弱、政策目标指派错位是导致入世以来我国棉花产业安全表现较差的根本原因。 相似文献
