制造业投入服务化对碳生产率影响的理论建模和实证检验——以珠三角为例

制造业投入服务化有利于制造业提高劳动生产率,且具有生态效益。在短期内,制造业服务化的发展会引起碳生产率的降低;但随着制造业服务化发展到一定程度,服务化对碳生产率的负向影响转为正,促进制造业碳生产率的提高。碳生产率与制造业服务化之间存在非线性关系且呈U型。     

Agricultural Productivity,Business Services,and Comparative Advantage

By explicitly incorporating both the intermediate business service sector and non-homothetic preferences, this study develops a two-good (the agricultural good and the manufactured good) model of trade that captures the role of agricultural productivity, which deepens the division of labor in the manufactured good sector. The level of agricultural productivity is found to determine the structure of comparative advantage: the country that has an absolute advantage in the agricultural sector also has a comparative advantage in the manufactured good sector.

Introducing spreadsheets into an intermediate financial accounting course: the results of a quasi-experiment

Previous research has revealed a measurable decrease in student attitude towards the use of computers when they are integrated into teaching. This fall in attitude is thought to reflect the initial diffculties encountered when attempting to use computers and learn acounting techniques at the same time. However, it is postulated that once the students' computer ability has achieved an adequate level, then attitude will recover. This paper reports the results of a continuing investigation into the attitude of second-year undergraduate accounting students towords the use of computers in their studies. The method used was to ask students to complete a questionnaire about their attitudes and self-assessed ability and to undergo a written test of their computer/spreadsheet Knowledge. These data were merged with those from earlier testing to give a two-year data set. The results indicate that the attitude of students to using computers generally continued to fall significantly. However, their ability to use computers and spreadsheets rose. In the case of spreadsheets, this rise in ability was significant. It was found that students who took, as options, additional courses which integrated computers had more positive attiudes and achieved higher scores in the computer Knowledge test than those who did not. This implies that the initial fall in attitude experienced in previous studies was not an isolated temporary phenomenon. The imporvement in ability is observed, but this did not have the expected effect.

中间汇率制度下货币、财政政策效应比较及政策建议

蒙代尔-弗莱明模型(M-F模型)研究了固定汇率制和浮动汇率制下财政、货币政策的有效性。将其拓展到中间汇率制度下发现,无论资本的流动性如何,扩张性的财政政策和货币政策基本有效,其效应介于固定汇率制和浮动汇率制的情况之间。实行中间汇率制度的国家在进行宏观调控时,最应该运用财政、货币政策搭配方法,此时政策效果最好。
