江苏省地质环境管理改革发展的目标与路径

江苏省现阶段的主要地质环境问题是由自然因素和人为因素造成和引发的。多年来,江苏省地质环境管理取得了很大成绩,但也存在不少问题。新时期加强地质环境管理要根据江苏省的实际,不断深化认识,健全法制,明确责任,突出重点,拓宽地质环境管理思路;要从政府、企业和社会三方面着手,构建保障社会科学发展的地质环境管理新机制,全面推进地质环境管理改革,为江苏省现代化建设"两个率先"的宏伟目标服务。     

Similarities and dissimilarities between the EU agricultural and rural development model and Romanian agriculture. Challenges and perspectives

The main aims of this study are to highlight the differences and the similarities between the European model of agricultural and rural development, and the state of play in the Romanian agricultural sector. Statistically speaking, the agricultural sector's indicators of the past two decades place Romania outside the family picture of the EU countries, with very slight resemblances, and very strong discrepancies between their economic, technical, and institutional characteristics. At present, competition-wise, farming and farmers in Romania are still strongly disfavoured in relation to their competitors in the old EU Member States. In Romania, the economic and institutional mechanisms have most often been devised to the disadvantage of agricultural production, by claiming that subsistence farming would be the sustainable way, and by channelling the added value to other sectors. An option to continue the agricultural policies of the past decades and to abandon the national support lent to agriculture would be particularly risky through its unpredictable and incalculable social and economic effects.     

Land use planning and health and well-being

This paper is concerned with the relationship between the planning of settlements and health. It gives a brief introduction to the issues before summarising the evidence in relation to a range of topics, concluding with some more speculative thoughts on likely future findings.Modern planning was invented in response to inhumane living conditions in 19th century cities. But in the last century the connection was lost. Only now, with concerns over climate change and obesity, is there beginning to be the realisation that the physical environment is an important determinant of health.The paper uses a particular model of this relationship based on eco-system and health determinants theories to structure the review of evidence. The review covers: lifestyle choices in relation to physical activity and diet, mental well-being and community, the local economy and income, health inequalities and strategic land use transport planning, pollution and urban form, and finally impacts on global ecology.There is now a growing consensus that while personal factors are critical in determining health, the urban environment exacerbates or mitigates health and well-being outcomes.The level of active travel (walking and cycling) and outdoor recreational activity is strongly affected by accessibility to local facilities. Access to green, natural environments, and to local social networks, are factors in mental well-being. The wider sub-regional pattern of housing, economic development, land use and transport is a determinant of social exclusion and therefore health inequalities. It also affects health-damaging pollution, adaptability in the face of climate change and the level of carbon dioxide emissions.We have literally been building unhealthy conditions into many of our towns and cities. But comparisons with the best cities in Europe indicate that it is possible to reverse the less desirable trends. Success depends, however, on more radical policies of local authority control over land and finance than any political party has yet advocated. It also requires collaboration between the full range of powerful public and private organizations that influence the built environment.Future research is likely to further strengthen these conclusions. It will become much more obvious that planning for health and well-being is not only the NHS, but about creating a health-promoting physical, social and economic environment.     

财税政策、工农业分工与农业生产率——理论分析与经验证据

本文基于动态分工演进,以自给自足的自然经济为起点,将秩序服务和财税政策纳入一个理论框架,结合超边际决策分析和一般均衡分析,考察在此过程中各个经济人的最优决策在市场上相互作用而内生的各种变化,揭示了财税政策作用于工农业分工和农业生产率的内在机制。然后,使用中国改革开放以来的数据对相关结论进行实证检验。模型分析表明,政府财税政策的实施在促进工农业分工水平提高的情况下,会扩大粮食生产的迂回化经济程度,进而推动粮食部门的农地生产率提升。就长期而言,单位面积的财政支农支出对农地生产率的提高有显著正向影响,在其他农业生产要素既定情况下,单位面积的财政支农支出每增加1%,农地生产率增加3.23%;从短期来看,单位面积财政支农支出对农地生产率的作用较弱,但在反向修正机制的作用下,最终会达到有效提高农地生产率的长期稳定均衡。另外,财政支农支出的增加促进了分工水平的提高,而分工水平的提高又推动了农业生产率的提升。
