The called paper presents logistics cooperation activities in European countries, which are put in the situation of establishment of ASEAN Economic Community, particularly South East countries. This will be considered as the experience in managing by government officers as well as the board management of logistics. The authors' methodology is almost descriptive, theoretical analyses. In addition, conducting information-related survey and in-depth interviews by experts will be considered in case of necessary. This paper focuses on Logistic Corporation leading to result in some benefits including bringing on effective in transportation, cutting cost, and saving time; improving the transportation connectivity among countries in ASEAN area; facilitating the construction of infrastructure and legal framework, and assisting to develop regional logistic activity. In this research, the authors focus on analyzing in the period before and after 2015, they attempt to investigate the turning point in the installment of ASEAN Economic Community, including 10 countries with the signed print by the prime minister in these nations. For future research, it is suggested that the cooperation is worth taking into consideration as the innovation related to management activities in microscopes (inside business) as well as macro scopes (countries) in logistics sector. Furthermore, lessons from the success of the European market are the basis foundation for the ASEAN Economic Community in setting up a common market in the field of logistics, shortening time to avoid mistakes and making the intended plan more possible to develop regional logistic activity. Logistic cooperation among nations has played an important and critical role in formation and development of country collaboration, creating the efficiency and capacity of trade among nations of region. Consequently, this paper can provide valuable pointers for shaping AEC. 展开更多

With the growth of the online market,demand for logistics and courier cargo is increasing rapidly.Accordingly,in the case of urban areas,road congestion and environmental problems due to cargo vehicles are mainly occurring.The joint courier logistics system,a plan to solve this problem,aims to establish an efficient logistics transportation system by utilizing one joint logistics delivery terminal by several logistics and delivery companies.However,several courier companies use different types of courier invoices.Such a system has a problem of information data transmission interruption.Therefore,the data processing process was systematically analyzed,a practically feasible methodology was devised,and delivery invoice information processing standards were established for this.In addition,the importance of this paper can be emphasized in terms of data processing in the logistics sector,which is expected to grow rapidly in the future.The results of this study can be used as basic data for the implementation of the logistics joint delivery terminal system in the future.And it can be used as a basis for securing the operational reliability of the joint courier logistics system. 展开更多

This study elaborates three things: Firstly is the current agricultural cooperatives management and their low farm performance in eight provinces in the eastern of Thailand where are the bases of Thailand famous fruits products. Secondly is to point out the key concepts of the theory of entrepreneur and the strength of it to assist the community development, to teach young people, adults and cooperatives members to prepare them to pertain good entrepreneurship that meets cooperatives concepts and principles. Thirdly is to give an example of research study that describes how to identify entrepreneurial capability of agricultural cooperatives members in Thailand, dependent variable is qualitative or binary, we use "odds value" or probability of success over the probability of failure to identify the set of odds value, and use exponential function to transform the odds value to be the log of odds or Logit model. If probability of entrepreneur is over the cutting point of 0.8, it implied that members are pertained high entrepreneurial capability and vise versa. The first step of research is the analysis of five year panel secondary data during 2011-2015, collected from Cooperatives Auditing Department. Eight groups of 679 numbers of data from 215 cooperatives were calculated, data were divided by the number of member. These eight independent variables are Total income per member, Total equity per member, Net profit per member, Co-ops operating capital per member, Total cooperatives capital per member, Total deposit per member, Total asset per member, Number of member. Qualitative data are the four sizes of cooperatives: large, big, medium, and small. Qualitative data are the only one intervening variable in the model. Secondary data found that only four quantitative independent variables effect to entrepreneurial capability. Total asset per member, and Total income per member had negative effect, but Net profit per member, and Cooperatives capital per member had positive effect. It means that if cooperatives acquire more and more asset, cooperatives will have more burden of debt or equity and probability of entrepreneur will be decreased. If cooperatives gain more and more income to the firm, it means the complex organization or the cooperatives will success but the individual member who is individual finn will get loss. Cooperatives capital per member and Net profit per member have positive effect. Because cooperatives capital were gained from residual and after the allocation of cooperatives surplus to be patronage refund according to the volume of business which member had done with the cooperatives and dividend pay out to member according to the number of stocks they held for their saving with the cooperatives. For qualitative variable, large and medium size of cooperatives had no any effects, but small size of cooperatives had more effect than the big size. It implied that big cooperatives who had more and more number of members have more and more burden. Small size of cooperatives is similar to individual firm of each member. Thus, optimum size of cooperatives is suitable for their service and efficient management, if the size of business volume increasing continuously, the quality of service will decrease, because almost cooperatives organization is pricing at break even point. Second step is a primary survey of data from Rayong province. Seventy-five samples of cooperatives members have not recorded their business information, both revenue and cost. We cannot use logistic regression to run the second model, but only Multiple Regression Analysis (MRA). MRA results identify that the cooperatives profit of each member depends on three variables: (1) sales, (2) member responsibility (not board member responsibility or Management responsibility), (3) member's level of education. Suggestion and recommendation is that agricultural cooperatives members in Thailand still have to improve their entrepreneurial capability by recording all information related to business functions and prepare financial record to represent efficient use of resources to meet member and community's needs. 展开更多
