农村集体土地征收补偿中存在征收补偿标准偏低;农民对补偿金数额不满意;公正、合理是制定补偿标准最需要考虑的因素;补偿的补偿方式单一;补偿金归属问题令人担忧;补偿中的法规、政策等信息不透明等问题.其主要原因有三个方面,一是城市化发展不可避免地损害了农民的利益;二是公共利益名誉掩盖下的政府利益本位损害了农民的利益;三是农村集体土地征收补偿标准计算方法背离市场基本价值规律.因此,要从五个方面来完善农村集体土地征收补偿,一是建立城乡统一的土地流转市场;二是科学制定农村集体土地征地补偿标准;三是增设集体土地产权出让制度;四是公开农村集体土地征收补偿程序信息;五是转变政府职能,依靠政策法规和市场机制行事. 相似文献

Every day, a blood center must determine a set of locations among a group of potential sites to route their vehicles for blood collection so as to avoid shortfalls. In this study, a vehicle routing problem is modeled using an integer programming approach to simultaneously identify number of bloodmobiles to operate and minimize the distance travelled. Additionally, the model is extended to incorporate uncertainty in blood potentials and variable durations in bloodmobile visits. Optimal routings are determined using CPLEX solver and branch-and-price algorithm. Results show that proposed algorithm solve the problem to optimality up to 30 locations within 3600 s. 相似文献

Using data from China Annual Survey of Industrial Firms and addressing potential endogeneity problem, we find that corporate tax burden in China is procyclical during recessions and countercyclical during booms. The cyclicality is stronger for enterprises whose corporate income taxes are levied by Local Tax Bureau (LTB). Procyclicality of corporate tax burden during recessions is larger for enterprises located in county, non-state-owned enterprises (non-SOEs), non-high-tech enterprises and large-medium enterprises. Furthermore, tax quotas and growth targets of local governments enhance procyclicality during recessions and the countercyclicality of corporate tax burden during booms. Tax collection and government spending are important channels through which tax quotas and growth targets affect the cyclicality of corporate tax burden, respectively. This paper provides important policy implications for China during economic recessions. 相似文献

As the Internet of Things (IoT) begins to dominate the technology landscape, there will be new products and services that will become technically and financially feasible. Internet technologies and advancements in social interaction tools have led to an increase in the use of the crowd as a provider of business solutions. Yet, we have seen a mere fraction of the possibilities of crowdsourcing technologies. This is because most of the development, discussion, and research around crowdsourcing has focused on active-input crowdsourcing. However, the real transformative pressure will come from passive sources of data generated primarily by developing and growing sensor technologies. This next generation of crowdsourcing will be a game changer for entrepreneurial opportunities. As crowdsourcing systems proliferate, more input will be acquired from sensors, artificial intelligence, bots, and other devices. As a result of this explosion, the variety of product and service opportunities will swell as entrepreneurs become more aware of technologies merging—such as the combination of crowdsourcing, sensors, and big data into a new type of entrepreneurship: sensor-based entrepreneurship. The purpose of this research is to contribute by (1) clarifying the next generation of crowdsourcing and (2) developing and presenting a framework to help sensor-based entrepreneurs plan, develop, and map their new products and services. 相似文献

Community forest plantations are a common intervention in developing countries. We use household and remote sensing data from Orissa, India, to estimate welfare effects of community forest plantations, in terms of the value of decreased collection times plantations afford users. A selection model, accounting for possible jointness in site location and productivity, is used to estimate collection production functions for different household labor categories in natural and community forests. Two measures of an opportunity cost of time are used to determine welfare effects of time saved due to community forests. We find access to community forests is important to marginal productivity of different labor categories, but to different degrees, highlighting the need to disaggregate household data when analyzing these interventions. We also find substantial welfare improvements from time savings for many households and villages. 相似文献
