To analyze China’s fluctuating situation of the factor input and aggregative productivity is not only the main method to seek the source of the economic growth but also the main way to weigh the level of economic growth quality.As to economic growth ofa country,the improvementofthe productivity is extremely important.The growth of the output can be realized through two kinds of ways: increasing the quantity of factor input of or improving the efficiency of the input and output.There fore, the level of economic growth quality does not mainly depend on the amount of invested factor,but the importance of improving the productivity since resources are rare. The relative improvement of efficiency in use of the invested factor marks the economic growing quality.So,in order to understand the economic growth quality of China to some extent, it must analyze Chinese factor input and aggregative productivity. This is the main topic that this text will be probed into. 展开更多

Research question is how theory affects the performance. Answer might become thorough competence of professionals and task performance. With this sense, two case studis are obtained from Drucker's works (2009; 2015). Therefore, research method covers case study approaches. Furthermore, firms produce national GDP in an economy. There are several functions in firm management, and managers operate those functions. They are logistics, supply, stock, finance, accounting, marketing, production, etc. All have managers such as accounting manager, finance manager, marketing manager, etc. Performance of managers is crucial to fLrm performance. Because performance of managers might become one determinator of firm performance. Therefore, HRM may have an impact on GDP through managers. Because productions and sales of firms affect GDPs on an economy. Moreover, professionals or managers must have theoretical knowledge in their field. Because theoretical knowledge increases their performance at work. In conclusion, study reveals that managers may have impact on firm performance; and theory may increase task performance of employees. 展开更多

Based on the growth rates of population, Gross Domestic Products (GDP) and agriculture productivity, the areas of deforestation were predicted in Jutp ani village, Chitwan district, Nepal by Area Production Model (APM). Through the APM simulation in this study, all of forestland will be transferred into agricu ltural land in 2030 at the rate of 24% per year on the current productivity. And if the productivity of subsistence food crop is assumed to increase at the rate of 1%, the productivity of market crop and export crop increase at the rate of 2% annually, deforestation rate will decrease to 17% per year, but only 124 hm2 forest land will be left till 2038. The agriculture productivity is a very impor tant factor for the deforestation, so intensification of agriculture management is more important. 展开更多

In India, the construction industry plays an important role in the economy of the country. It employs a sizeable portion of the work force, contributes largely to the gross domestic product (GDP) of the country, and is seen as a key catalyst for the growth and development of the Indian economy. The industry, however, is beset with many challenges, including delivering projects within projected costs and delivery dates and at the right quality to increasingly discerning clients. It is because of this that project management has assumed so much importance with the project manager seen to be a critical resource in the project achieving its objectives. However, the role of the project manager is still ambiguous. These research hypotheses that the role the project manager ought to play is that of a leader. It is only when project managers assume leadership roles that construction projects achieve objectives measured against time, cost, quality, and customer satisfaction. A quantitative approach was followed in this using both theoretical and analytic methods. The theoretical studies revealed the qualities, skills, and competencies that a project manager ought to possess and the links between the project manager assuming a position of leadership and the project achieving its objectives. The main data collection tool in the analytic method was an online questionnaire administered to 20 project managers of construction projects in India. It was found that while the Indian construction industry does recognize the significance of project managers, their role is relegated to administrative, monitoring, and supervision tasks. There is an overwhelming focus on technical skills. In those cases, where project managers were involved in all the stages of the project and possessed a gamut of managerial, technical, human, and interpersonal skills, there were substantial differences in terms of time, cost, quality, and customer satisfaction in the projects administered by them. The importance of this research stems from its alerting the construction sector in India to the true role that project managers ought to play. If it serves in a shift in the perception of the role of the project managers, this research would have served its purpose. 展开更多
