This study aims to evaluate the distributional effect of the governmental rice policy in Japan on producers, consumers, and government expenditures from 1986 to 2010 using a partial equilibrium model. Policy measures include government purchase of rice, output payment, and acreage control. The simulation result shows that acreage control has been the principal policy measure for transferring income to producers, especially since the enforcement of the WTO Agreement on Agriculture. Acreage control is the policy measure with the lowest total efficiency and highest budgetary efficiency. This result implies that the government’s goal of transferring income to producers with minimum government cost has been achieved through a combination of policy measures. 相似文献

This study examines whether signing auditors from rice planting regions affect audit quality. Using a sample of 12,223 firm-year observations from the Chinese stock market over the period of 2004–2015, our findings reveal that signing auditors from rice regions are significantly negatively associated with the likelihood of unclean audit opinions, suggesting that signing auditors with rice culture are more likely to succumb to the managers and hamper independence, and thus are more inclined to issue favorable audit opinions, and eventually impair audit quality. Furthermore, audit firm size and industry expertise attenuate the negative relation between signing auditors with rice culture and audit quality. In addition, above findings are robust to a variety of sensitivity tests using different measures of audit quality and signing auditors from rice cultivating areas and our conclusions still stand after using the Heckman two-step approach, placebo test and differences-in-differences method to address the potential endogeneity problem. 相似文献

Irrigation water productivity in Cambodian rice systems 总被引:1,自引:0,他引:1
Knowledge of the marginal productivity of water is crucial for decisions about its allocation between uses, which is particularly important in the context of increasing competition for water. Using primary, plot‐level panel data, this article estimates the marginal productivity of water from supplementary irrigation in lowland rice systems in Cambodia, taking into account farmer and plot heterogeneity as well as self‐selection of supplementary irrigation. Our estimates indicate a range of elasticities for rice output with respect to water inputs of between 0.057 and 0.069 for wet season production, substantially lower than previous estimates based on either aggregate or trial data. We discuss the policy implications of these results, in particular with respect to the utility of demand management policies and the challenges they pose to the decentralization of water management to Farmer Water Users Groups. 相似文献

Cognition of disaster risk in a tourism community: an agricultural heritage system perspective 总被引:2,自引:0,他引:2
Yehong Sun Hongjian Zhou Geoffrey Wall Yunjie Wei 《Journal of Sustainable Tourism》2017,25(4):536-553
Cognition of risk is the first step in reducing disaster damage and losses. In this study, risk cognition in the Hani Rice Terraces, the core tourism attraction in Yuanyang County, Honghe Prefecture, Yunnan, China, is analyzed based on field survey and participatory geographic information system (GIS). The results show that tourism communities have cognition of risk; are more sensitive to hazards (especially drought); have more severe potential damage and losses from hazards; and also have more enthusiasm to adapt to disaster risk, when compared with a non-tourism community. On disaster vulnerability maps, the tourism communities identified the unique “Forest – Village – Terrace - River” landscape while the non-tourism community only recognized the terrace and the village as the main elements affected by hazard. Also, the tourism communities had deeper understandings of drought, flash floods and landslide disaster risks. A conceptual model based on “Pressure – State – Response” relationships is put forward to explore the situation in which, in the tourism community, terraces have a greater variety of functions and enhanced values resulting in the spatial expansion of hazard effects. 相似文献

Production risk,risk aversion and the determination of risk attitudes among Spanish rice producers 总被引:1,自引:0,他引:1
Agricultural production is subject to risk and the attitudes of producers toward risk will influence input choices insofar as these affect production risk. Risk attitudes in turn may be affected by certain socioeconomic characteristics of producers. Using 2004 survey data from a cross‐section of 130 Spanish rice farms, we estimate risk‐aversion coefficients of farmers and investigate the influence of a series of socioeconomic variables on their risk attitudes. Our results show that farmers exhibit risk‐averse behavior and that risk attitudes are related to a series of socioeconomic characteristics. In particular, the belief that the farm will continue after the producer retires is found to increase the degree of risk aversion, while age is found to have nonlinear effects on risk aversion. Off‐farm income, especially from nonagricultural activities, is found to reduce risk aversion. Neither the educational level of the producer nor the presence of dependents on the household is found to have an effect on risk preferences. Regarding the production technology, we find that land, labor, and fitosanitary products are risk‐reducing inputs, whereas capital, seeds, and fertilizer all increase risk. 相似文献

Using a generalized error correction model, this article measures and compares market integration for export cash crops versus imported food crops for Mali and Nicaragua, and computes transmission elasticities between changes in the goods’ border and domestic prices. Both Mali and Nicaragua obtain the bulk of their export revenue from a particular agricultural commodity—cotton for Mali and coffee for Nicaragua—and both import the same key staple food of rice. To reap the economic gains from this trade specialization, the two countries’ agriculture must be well‐integrated into world markets. The two countries present an important policy contrast that affects their degree of world market integration and price transmission. In Mali, a parastatal enterprise controls its cotton industry, while Nicaragua has less state direction over agriculture. Reflecting this difference, the results show that for both its main export and import commodity, Nicaragua is more integrated into world markets and has higher price transmission than Mali. The results for Nicaragua also show much higher integration and price transmission for its main agricultural export (coffee) than its major import (rice). 相似文献

Impact of land fragmentation and resource ownership on productivity and efficiency: The case of rice producers in Bangladesh 总被引:5,自引:0,他引:5
The paper analyzes the impact of land fragmentation and ownership of resources on productivity and technical efficiency in rice production in Bangladesh using farm level survey data. Results reveal that land fragmentation has a significant detrimental effect on productivity and efficiency as expected. The elasticity estimates of land fragmentation reveal that a 1% increase in land fragmentation reduces rice output by 0.05% and efficiency by 0.03%. On the other hand, ownership of key resources (land, family labour, and draft animals) significantly increases efficiency. The mean elasticity estimates reveal that a 1% increase in family labour and owned draft animal improve technical efficiency by 0.04% and 0.03%, respectively. Also, a 1% increase in the adoption of modern technology improves efficiency by 0.04%. The mean technical efficiency in rice production is estimated at 0.91 indicating little scope to improve rice production per se using existing varieties. Policy implications include addressing structural causes of land fragmentation (e.g., law of inheritance and political economy of agrarian structure), building of physical capital (e.g., land and livestock resources), improvements in extension services and adoption of modern rice technology. 相似文献

Reduction in nitrogen fertilizer use results in increased rice yields and improved environmental protection 总被引:1,自引:0,他引:1
Overuse of nitrogen fertilizer represents a considerable environmental problem globally, but especially in China. Recently, a recent approach on an experimental scale based on the diffusion of the so-called Three-Control Technology (TCT) successfully alleviated the overuse of nitrogen fertilizer in southern China villages in the Guangdong Province, serving as a reference point for other rice-producing countries tackling similar challenges. Here, we assessed the correlation between rice yields and reduction in the use of nitrogen fertilizer following the introduction of TCT. Our study was based on the collection of primary data from 248 households randomly selected from four rice-growing areas of Guangdong Province, China. Our results show that TCT significantly improved the efficiency in the use of nitrogen. Crucially, participating farmers, including both full adopters and partial adopters, were found to fundamentally change their application practices of nitrogen fertilizer, resulting in major improvements in the local soil and water systems. 相似文献
