[Method] The policy simulation platform based on CGE model was constructed by integrating policy simulation, CGE model and Decision Supporting System (DSS). The scenario analysis method was used to analyze the agricultural subsides policy simulation through empirical analysis. [Result] Farmers were the main beneficiaries of increasing agricultural production subsidies, which increased farmers' income and improved the export of agriculture products. The prototype system could solve the problems in actual policy simulation. [Conclusion] The results lay the foundation for the quantitative study on agricultural subsidy policy in China.展开更多

First, enterprises do not necessarily share the same expectation for future demand of a promising industry. Second, in its model, overcapacity is explained as a deviation from equilibrium under the incomplete information hypothesis, which is in fact nothing but normal in a market economy. The prime reason for overcapacity resides in the fact that local governments are engaged in a subsidy competition to attract investment. We endeavor to illustrate the following via modeling: the subsidy effect produced by local government's offering of cheaper land and matching loans results in less investment from companies. Under this circumstance, enterprises channel a disproportionate amount of funding to building production capacity, which overloads the entire industry. To address the problem, reforms are needed in land property, environmental protection policies, and financial and fiscal systems.展开更多

It is started with the connection between agricultural insurance and financial subsidy. It is really necessary and crucial to implement the financial insurance due to the bad operational performance, especially in the developing countries. But the sub- sidy should be provided more rationally because financial subsidy has lots of negative effects. A model in competitive insurance markets developed by Ahsan et al (1982) and a farmers' decision model are developed to solve the optimal subsidized rate. Finally, the equation is got to calculate it. But a quantitative subsidized rate is not made here because the calculation should be under some restricted conditions, which are always absent in the devel- oping countries. So the government should provide some subsidy for the ex ante research and preparation to get the scientific prob- ability and premium rate.展开更多

In this context, this paper assesses the competitiveness of Indian cotton producers and potential implications for India as a competitor in the world cotton market. This paper developed an updated estimate of the costs of cotton production in India and developed representative farm models for cotton production in three important cotton production states (Gujarat, Maharashtra and Andhra Pradesh) of India. In this research, Rapid Rural Appraisal (RRA) methodology has been adopted to collect information for developing representative farm models. These models are further subjected to stochastic simulation to understand the impact of government policies like subsidies to various inputs on farm level profitability and ultimately on the competitiveness of Indian cotton in international markets. This paper also analyzed the impact of national fiber policy of the government of India on the cotton processing sector in India. The results demonstrate that the net income of the cotton farmers will decrease considerably without the presence of fertilizer subsidies. The study also concludes that if the objectives of the national fiber policy are fulfilled, India will export more of value added cotton products like textiles and garments rather than raw cotton.展开更多

Our empirical research has found that after the release of the "eight-point regulation ", investors responded negatively to private frms and positively to SOEs. Such market response is more significant for firms with a high degree of rent-seeking. Further research has found that rent-seeking helps both SOEs and private firms receive more subsidies from the government. While government subsidy from rent-seeking is conducive to the performance of private firms, it is not the case for SOEs. This implies that rent-seeking activities serve as a "lubricant'for private firms but have a "stumbling block" effect for SOEs.展开更多

Chinese government popularized the beneficial agronomic measures in the process of wheat straw returned field by mechanization. The agronomic measure was reducing the wheat straw stubble height(WSSH) not more than 20 cm.However, local government didn't apply and disseminate the measure, because in practice the cost of fuel consumption was high, and the operation time of harvesting was longer than ever. The machinery operators and farmers needed to support extra fuel cost and time if they took government's advice. In fact, the objective subsidy policy of fuel cost on reducing WSSH was not been formulated by all levels of government. Therefore, the set of agronomic measure couldn't be popularized in main wheat production area of North China. Our research addressed to master the changing feature of fuel cost and mechanical efficiency,seeking suitable subsidy standard, providing some useful and constructive suggestions to improve subsidy policy of fuel consumption cost for national government department. The study carried out the tracking experiments of the operation efficiency and fuel costs of farm harvester in the situation of different WSSH in 2010 in Xushui District of Hebei Province. In conclusion, the operation time of harvesting decline and machinery fuel consumption cost increased along with the decreasing of WSSH. First for the older harvester, the operation efficiency would decline by 18.7% when the WSSH changed from 20 cm to 10 cm, the cost would increase 4.7%, exact cost was 152.2CNY per hectare. For the new harvester, the operation efficiency would decline by 39.9% when the WSSH changed from 20 cm to 15 cm, the cost would increase 4.6%, exact cost was 368.4CNY per hectare. We provided about 375 CNY per hectare to the mechanical operators and farmer who attended this project, and they were willing to accept the subsidies. We also put forwards some policy suggestions on promoting agronomic measures of reducing WSSH including strengthen the construction of agricultural machinery service system, practise a special fuel consumption subsidies of agricultural machinery and open up new paths for combine sales and circulation.展开更多

As many distribution generators(DGs) are integrated in distribution systems, analysis of MG formation necessity is conducted from the aspect of DGs. In order to maximize the profit brought by DGs and to earn money from arbitrage, it may be necessary for customers to combine their DGs and loads and to construct an MG to obtain maximal control ability. A game model is built to emulate trading between MGs and the distribution system based on MG power control, in which both trading profit and outage cost are considered for each MG. Nash equilibrium(NE) is calculated, and sensitivities of NE to some boundary conditions are studied. The results show that variable MG trading prices with appropriate net generation cost(i.e., DG generation cost minus government subsidy price) may encourage the growth of MGs. Government subsidies, generation costs, and trading prices may also affect DG use, and therefore they may impact customer motivation to build MGs.展开更多
