基于互联网大数据的CPI舆情指数构建与应用 总被引:2,自引:0,他引:2
研究目标:基于互联网大数据构建CPI舆情指数辅助预测CPI。研究方法:提出了一种构建CPI低频与高频舆情指数的统计方法,并通过选用2006年6月至2015年12月的数据验证了该方法的有效性。研究发现:相关关键词的搜索热度指标具有领先CPI的预测作用,依此建立的CPI舆情指数有助于改进CPI预测精度。研究创新:揭示了基于相关关键词的搜索热度指标与CPI的非线性关系,提出了一种基于门限回归的CPI低频舆情指数构建方法;使用动态因子模型估计出了CPI高频舆情指数。研究价值:预测CPI时可辅助利用基于大数据构建的CPI低频与高频舆情指数信息。 相似文献

基于ESDA-GWR的粮食单产及其驱动因子的空间异质性研究 总被引:13,自引:0,他引:13
在耕地面积扩展有限和城市化高速发展的背景下,粮食单产的区域差异对我国粮食安全具有重要意义。以我国31省(市、自治区)为研究单元,借助ESDA和GWR模型,结合我国各地自然条件的差异及其经济发展类型,揭示我国粮食单产的区域差异及其驱动因子的空间异质性。结果表明:1999—2008年,中西部地区粮食单产的增产对全国粮食产量的贡献越来越显著,75%的粮食单产增长潜力较大的区域集中在中西部;粮食单产存在着显著的空间相关性,各省域粮食生产重心发生移动,由传统的"东部为主"逐渐"北上西进",向中西部地区欠发达省份集中;不同区域粮食单产的驱动因素呈现为一种非均衡联动的局域性特征,化肥施用量对粮食单产的影响在两个时间断面中差异最大,1999年回归系数全为正值,而在2006—2008年出现负值,这表明部分地区化肥对粮食单产的边际效应已经达到递减阶段。因此,应结合我国不同区域当前粮食单产的现状和驱动因子的效应机理,积极采取相应的有效措施以保障我国的粮食安全。 相似文献

银行业的价值评估对于推进金融体制改革存在重要意义,本文从价值评估文献综述入手,建立了一个两步骤的统计学模型,首先通过因子分析得到影响银行价值的主要成分,然后通过多元线性回归检验银行规模、经营业绩和流动性对银行股票价格的影响,实证结果显示:股权分置改革并未如预想的那样对股票价格有明显影响,中国银行业主要盈利来自于存贷款利差收入。 相似文献

The available literature on self-initiated expatriates (SIEs) is generally based on the assumption that SIEs are protean in character and manage their careers independently. The current qualitative empirical study offers an alternative to this assumption, using 23 interviews with Western SIEs employed by local organizations in China to examine how and why SIEs target obtaining a labour market fit through career self-management behaviour, particularly in culturally distant career contexts. The assessment of the career self-management behaviour of Western SIEs was undertaken using King's framework (2004). Three approaches to self-management behaviour were identified based on the motivation and outcome expectations of SIEs: labour market entry, employability maintenance and career advancement. The research illustrates the flexible and dynamic nature of career self-management behaviour and reflects individuals' revised career expectations and the employment context of the host country. The findings contribute to the extant theory on SIEs by illustrating emerging means of realizing international careers in cross-cultural career contexts, and the significance of third-party initiatives supporting expatriation facilitated by the Internet and social media. 相似文献

Oil and natural gas reservoirs typically span multiple productive leases so that no owner has rights to the entire stock of resource, resulting in production externalities. Previous literature has examined the effectiveness of government regulation in Texas and Oklahoma in abating these externalities, finding Oklahoma to be more successful in unifying common pools and securing property rights. Using regression discontinuity design, we quantify the impact of regulatory difference between the two states. We find that Oklahoma produces an average of 3361 more barrels of oil over the life of a well, relative to Texas. Given the maturity of the fields in question, the result underscores the continuing importance of addressing common pool externalities even after the primary phase of recovery has largely been completed. 相似文献

Applying the hedonic approach to land prices, this article investigates the capitalization of public services and pure amenities in a cross section of German communities. Possible spillover effects from neighboring municipalities are explicitly included in the analysis and prove to be of considerable importance. Estimates of the impacts of local attributes on land prices are obtained taking into account the spatial structure among unobserved variables. The results confirm that differences in land prices are largely attributable to local conditions and policies. This implies a significant degree of mobility as well as high estimation of local attributes on the part of German households. 相似文献

This article provides empirical evidence and contributes to theory building concerning business model fit and dynamics in the area of solutions business. Business models are seen in this context as going beyond considerations such as offerings and internal processes or even relationships, and as including network and market considerations. Indeed the paper highlights the fact that a business model is not firm-focused, nor dyad-focused, but rather network-, and even market-focused, demonstrating that a business model is not static, but dynamic. Manufacturer and customer continuously shift form and content of their respective business models to adapt both to the needs of the counterpart and to market context. A qualitative case study approach is adopted, with subsequent content analysis. The case study relates to the aerospace industry with focus on a complex engineering firm, one of the largest aircraft manufacturers in the world, its customer — a national airline — and their network partners of various kinds. The data were collected through multiple face-to-face interviews with managers in both companies, as a part and parcel of a network of actors that influences and is influenced by the supplier–buyer relationship. Relationships over time between these firms and network partners are described, highlighting the interplay of products and services related to the provision of solutions. Findings highlight the dynamic nature of business models over the relationship lifecycle between supplier and customer in a complex engineering environment, and the need for reciprocal adjustment of models. 相似文献
