Prediction of Labor Force＇s Supply and Demand in Urban Areas of China

In the recent years, with the promotion of reform and the exposing of some profound contradictions, the problem of unemployment is outstanding day by day and becomes an important problem in present China＇s economics. Based on the data offered by China Statistical Yearbook： 2003, the short-term supply and demand of labor force in urban areas of China is predicted in this paper.     

我国农产品出口信用保险问题探讨

随着农产品国际市场竞争的不断加剧，企业因风险而遭受损失的情况越来越普遍，出口信用保险作为一种政策性贸易促进措施可以发挥重要作用。当前，我国农产品出口信用保险总体上呈现出良好的发展态势，但同时也面临着许多不容忽视的突出矛盾和问题。因此，必须进一步优化宏观政策环境，创新保险服务模式，全面提升农产品出口企业的风险意识和管理水平。     

Testing the intertemporal labor supply model: are jobs important?

The neoclassical life-cycle labor supply model assumes that hours of work are determined by labor supply choices alone and does not include a role for employers or job distinctions. An alternative model in which employers have an interest in employee hours and changing jobs is costly may reconcile weak and conflicting evidence regarding the neoclassical model. An important implication of such an alternative is that individuals may face hours constraints on a job and thus can choose hours freely only between jobs. This paper tests several implications of the neoclassical model against this alternative model of hours determination. Using a unique panel of individuals and jobs constructed using data on women from the 1988–1992 Panel Study of Income Dynamics, I compare hours variances and labor supply elasticities measured within and between jobs. Results provide some evidence against the neoclassical model and suggest that ignoring the role of employers in determining hours of work can lead to downward bias in estimates of labor supply elasticities.     

Energy Technology Advancement and Energy Policy Selection in China

This paper studies the system structure of energy technology advancement and sticking points of energy technology advancement in China. Then the marketing competence and supply and demand makeup of some primary kinds of energy in China are predicted. At last the policy selection to promote energy technology advancement is put forward for the future in China.     

Nonlinearity in dynamic adjustment: Semiparametric estimation of panel labor supply

We estimate a semiparametric dynamic panel data model by the local linear kernel method and we interpret the slope of the nonparametric component function as a varying slope coefficient. Thus, the slope coefficient is a smooth, but otherwise unknown, function of some of the regressors. A Monte Carlo experiment is reported to examine the finite sample performance of the local linear estimator. We apply the estimation method to a labor supply equation for men from the triannual Survey of Income and Program Participation (SIPP). Specification tests based on the estimated labor supply elasticities, partial adjustment coefficients, and residuals demonstrate the improvements from a semiparametric partially linear model. Our empirical results point to a need by economists to revisit the issue of the speed of labor market adjustment to policy induced shifts in labor demand and to take more formal econometric account of heterogeneity in wage effects when studying the distributional consequences of tax reforms for labor supply earnings.

企业横向并购后的内部供应链整合

横向并购已经成为企业快速扩张的一种有效手段，而内部供应链的整合将会决定横向并购行为的成败。横向并购后的企业为避免原有的两条供应链各自为战，并且为整合外部供应链打下基础，必须进行内部供应链的整合。通过运用业务流程再造、采用先进的预测方法、采用供应商管理库存以及延迟产品差异化等策略可以实现提高内部供应链效率和响应速度，提升供应链柔性的内部供应链整合目的。

供应链管理影响因素及评价指标分析

本文认为,供应链凝聚、信息获取能力、区位优势以及信息共享是影响供应链管理成功的四个主要因素,对这四个变量难以直接进行测量。供应链管理成功影响因素测评指标体系是一个多指标的结构,运用层次化结构设定测评指标,从而清晰地表述供应链管理成功影响因素测评指标体系的内涵。供应链管理成功影响因素是总的测评目标,为一级指标,即第一层次;供应链管理成功影响因素中的供应链凝聚、区位优势、信息获取能力、信息共享等四大要素为二级指标,即第二层次;根据各要素的含义和内容,将四大要素(二级指标)展开为具体的三级指标,即第三层次。     

Research on Sustained Development of Supply Network Based on HITS Conception

21st century is a new century with the conception of ＂centralized on customers＂ instead of ＂centralized on products＂. A key feature of nowadays business is the idea that it is supply chains＇ competition, not companies. The present researches to supply chain strategy most concentrated on the operation level. However, the support level which consists of technology, institution, human resource and surroundings is also a factor of cardinal significance to impact the implement of supply strategy. This paper does further research on HITS （Human resource, Institution, Technology and Surroundings） factors to support the supply network sustained development.     

In-work policies in Europe: Killing two birds with one stone?

Generous social assistance has been held responsible for inactivity traps and social exclusion in several European countries, hence the recent trend of promoting employment through in-work transfers. Yet, the relative consensus on the need for ‘making work pay’ policies is muddied by a number of concerns relative to the design of the reforms and the treatment of the family dimension. Relying on EUROMOD, a EU-15 integrated tax-benefit microsimulation software, we simulate two types of in-work benefits. The first one is means-tested on family income, in the fashion of the British Working Family Tax Credit, while the second is a purely individualized policy. Both reforms are built on the same cost basis (after behavioral responses) and simulated in three European countries suspected to experience large poverty traps, namely Finland, France and Germany. The potential labor supply responses to the reforms and the subsequent redistributive impacts are assessed for each country using a structural discrete-choice model. We compare how both reforms achieve poverty reduction and social inclusion (measured as the number of transitions into activity). All three countries present different initial conditions, including existing tax-benefit systems and distribution of incomes and wages. These sources of heterogeneity are exploited together with different labor supply elasticities to explain the cross-country differences in the impact of the reforms.
