This paper investigates variability of farm income and revenue on upland farms in the Tokachi district. The main results are as follows. First, variability of farm income, revenue and agricultural products sales differs depending on type of farming and farm size. Variability on vegetable farm entities is larger than on single dry field farm entities. The larger the farm size, the larger the variability is on single dry field entities. Second, there is a correlation between the coefficient of variation of agricultural product sales and the coefficient of variation of revenue. But there is also a weak correlation between the coefficient of variation of agricultural product sales and the coefficient of variation of farm income. Third, under stable management, the marginal profit rate is higher and fixed cost is lower than under unstable management.
The purpose of this study is to examine whether farmers are likely to reduce production costs by choosing between new technologies (6-row beet harvester and 6-row beet transplanter for short paper pots) and a conventional one when they replace their harvester and transplanter. As a result, the following became clear. First, when a farm introduces new technology for self-sufficiently, the production cost will always exceed that of the conventional technology. Therefore, a contractor organization is required in order to reduce production costs by choosing new technologies. Second, when the farm continues to cultivate sugar beet in spite of lack of labor, it will be effective to introduce the new technology.
The total factor productivity (TFP) of soybean production was measured from 1987 to 2015 by the Tornqvist index for different production scales in the large-scale farming region Hokkaido and other remaining regions. The TFP increased gradually in both the Hokkaido and other regions, though the former continuously increased grain yield per unit area (YU) while the latter decreased it. The latter region increased the proportion of middle-to-large scale farmers with relatively high TFP and low YU, thereby resulting in the overall TFP increase and YU decrease in Japan. Results suggest that the two regions adopted different strategies to increase TFP.
In this study, a threshold vector error correction model was used to examine the vertical price transmission of the Japanese beef market from September 2001 to December 2017. The main findings are as follows. First, there was asymmetry price transmission in the Japanese beef market. In particular, an error correction model of cattle price revealed the asymmetric price transmission in the period from September 2006 to December 2017. Second, calf prices and cattle prices played a major role in price adjustment. In the period before August 2006, the asymmetry of price adjustment in calf price could be captured. Third, no causality for price transmission was observed during the period before August 2006 including BSE, but there was short run price causality for cattle, calf and dressed carcass prices on cattle price in the second period.
The purposes of this study are i) to analyze the determinants of profitability of beef cattle breeding management in Chifeng City, Inner Mongolia and ii) to identify the current managerial problems. The regression analysis based on the data collected by a farm management survey revealed that the farm net revenue was significantly affected by the number of cattle fed, cultivated land area, presence or absence of corn sales, shipping weight of a calf, and shipping rate. It was also found that small-size farmers are more likely to view the external environment as a problem and try to maintain the present management status, while large-size farmers are more likely to consider the lack of internal resources as a problem and try to enhance use of their own resources in order to expand their management.
We conducted a questionnaire and an interview about job satisfaction, which targeted 4 large-scale pig farm corporations in Japan. First, when we compared each corporation, the results showed that the more employees who had career aspirations, the higher the job satisfaction score. Next, when we compared by career aspiration, employees with career aspirations had a higher satisfaction score in every corporation. In addition, when comparing workers with career aspirations to workers who want to work long-term, there was a relation between their results. Considering the analyzed results of each question about job satisfaction, there was a significant difference among corporations. These results indicate that improving human resource management systems while considering the differences among the levels of job satisfaction can not only improve employees’ job satisfaction but also have an effect on the securement of the number of employees who aspire for promotion and on employees’ motivation for long-term service.
The purpose of this study is to verify the changing process of Full Utilization of Paddy Fields in Japan from literature surveys and statistical analysis. The main results are as follows. First, the policy up to the fiscal year 2018 is divided into the first half and the second half every five years. Second, the first half promoted the maximization of paddy field use, while the second half had the role of rice production adjustment. Thirdly, paddy field maintenance is becoming more serious as paddy fields are being reduced and policy concerns about uncultivated paddy fields are weakening.
Official agricultural statistics in 2019 revealed that the coverage of farmland area of large-scale farms has decreased. Using the case of Sakata, this study clarifies that this agricultural structure change was caused by the dissolution of community-based group farming. The results are as follows. By the incorporation deadline for community-based group farming, about half of such farms were incorporated, and the remaining half were dissolved. Some of the latter were large-scale farms with more than 100 ha, which caused a downsizing in the statistical agricultural structure of Sakata.
