FDI引入对中国就业效应分析

伴随着我国开放政策的深化和加入WTO,FDI的就业效应日趋成为学者们的重要研究课题。本文通过对FDI较为系统地分析,认识到FDI的就业效应更应该是一种间接和长远的效应,且其具有空间性和时间性特征。因此本文从FDI的关联性和长远的动态特征等方面对其就业效应进行分析。     

Personalized multi-period tour recommendations

During a trip planning, tourists gather information from different sources, select and rank the places to visit according to their personal interests, and try to devise daily tours among them. This paper addresses the complex selection and touring problem and proposes a “filter-first, tour-second” framework for generating personalized tour recommendations for tourists based on information from social media and other online data sources. Collaborative filtering is applied to identify a subset of optional points of interest that maximize the potential satisfaction, while there are some preselected mandatory points that the tourists must visit. Next, the underlying orienteering problem is solved via an Iterated Tabu Search algorithm. The goal is to generate tours that contain all mandatory points and maximize the total score collected from the optional points visited daily, taking into account different day availabilities and opening hours, limitations on the tour lengths, budgets and other restrictions. Computational experiments on benchmark datasets indicate that the proposed touring algorithm is very competitive. Furthermore, the proposed framework has been evaluated on data collected from Foursquare. The results show the practical utility and the temporal efficacy of the recommended tours.     

促进中国经济长期持续 均衡增长中的公共投资因素 ——基于1 489份调查问卷的统计分析

根据对北京等7个城市的1 489份调查问卷分析我国长期经济增长中的公共投资问题，发现制约和促进中国经济持续均衡增长的最主要因素是技术进步；为促进中国经济长期持续均衡增长，公共投资最主要作用是引导战略产业成长，公共投资最应该投向的领域是“科教文体卫”等公益项目，公共投资与GDP最合适比例应在10%左右，公共投资最应该发挥的是社会福利效应等，并提出提升公共投资促进中国经济长期持续均衡增长的相关政策建议。

Heterogeneous returns to chemical fertilizer at the intensive margins: Insights from Nepal

Increased fertilizer use is considered important for agricultural development in low-income countries. Promoting increased use of chemical fertilizer by lowering its price may be ineffective if demand is price inelastic. In theory, the price elasticity of demand depends on the returns to its use, but the evidence is scarce. Furthermore, while returns are often estimated for small changes in chemical fertilizer use, returns to larger changes in its use (intensive margins) are less understood. Through the inter-zonal comparisons in Nepal, we provide indicative evidence that greater returns to chemical fertilizer are associated with greater price elasticities of demand. Moreover, the evidence suggests that returns at the intensive margins, rather than returns to small changes, may largely account for inter-zonal differences in returns to chemical fertilizer within Nepal. The results suggest that better understanding the returns at the intensive margins is critical for effective agricultural inputs policies in developing countries.     

我国化肥价格波动与农民收入关系的实证分析

本文利用1978～2008年的时间序列数据,运用脉冲响应函数和方差分解技术考察化肥价格波动与农民收入之间的关系,发现化肥价格的波动与农民收入变化之间存在着双向的因果关系,即化肥价格的上涨导致农民增收缓慢,而化肥价格上涨的根本原因在于＂需求拉动＂和＂成本推动＂。今后必须从需求和供给两方面采取对策：一方面通过建立化肥直接补贴制度和化肥储备制度,从需求上控制化肥价格上涨;另一方面通过采用新型化肥生产技术和给予化肥生产企业生产用能以优惠政策,从供给上控制化肥价格上涨。     

我国农用化肥施用的影响因素——基于省际面板数据的实证分析

我国农用化肥施用量不断提高带来的环境污染问题日益严重。研究化肥施用的影响因素及其影响程度,为防止化肥滥施、保护生态环境提供依据意义重大。文章采用1999～2008年我国31个省(市、区)的面板数据,通过面板单位根检验、协整关系检验和多元回归方法分别对国内东、中、西三大区域化肥施用密度与其影响因素之间的关系进行了实证分析。研究结果表明,三大区域农民人均纯收入、人口规模对化肥施用密度具有显著的正向影响,三大区域化肥价格增长率、粮食种植面积比重、化肥产出效率对化肥施用密度具有显著的负向影响,三大区域种植产品生产价格、种植业劳动力数量、农产品国际贸易对化肥施用密度具有不同的影响效果或显著性。
