国有土地分配与转让的现状、问题与对策

近年来,国有土地分配与转让问题引起了全社会的普遍关注,成为我国国民收入分配不可或缺的重要内容。本文在简要介绍我国国有土地分配与转让现实状况的基础上,探讨了存在的主要问题,最后给出了解决问题的对策。     

深化农村各项制度改革,从根本上解决三农问题

目前,“三农”问题严重制约了我国整体现代化进程。造成“三农”问题的根本原因是农村的各种旧体制已成为生产力发展的障碍。因此,要彻底解决“三农”问题,必须深化农村各项体制改革,实现体制的全面创新。     

转轨时期我国小农经济改造思想演变与争议

改造小农经济是转轨时期社会主义建设的最艰巨的任务之一。本从家庭经营、规模经营、农业产业化、农村剩余劳动力、农地制度创新等5个方面总结了理论界对小农经济改造的争议与研究，并认为改造小农经济应以邓小平“两个飞跃”理论作为理论基础。     

论我国农民集体土地所有权

我国农村集体土地所有权法律地位不明的一个根本原因是缺少对农村集体土地的物权制度设计,传统上对农村集体土地的公有制设计是从政治经济的意义出发的。在坚持集体土地公有制的前提下,认可集体土地所有权是民法上的私权利大有裨益,由此也有必要赋予每一个“农民集体”以法人地位,并精心设计该法人的治理结构,从而成为确保我国社会主义公有制得以实现的一种良好的方式。     

"三农"问题新论——在城市化进程中解决三农问题

我国市场经济改革和经济发展的首要任务是农村的货币化和城市化,"三农问题"是当前我国经济结构中最重大的问题.在我国经济高速发展的同时,我国经济也存在着沦为"富人经济"的巨大风险.在这个问题上,提高农业劳动生产率和发展乡镇企业都不能从根本上解决问题,只有通过城市化、通过高速发展的经济来迅速转移农村剩余劳动力,实现农民市民化、农业工业化才能解决"三农"问题,才能使我国经济健康运行.     

乡村振兴视角下商业养老保险对土地流转影响研究

基于世代交叠理论和劳动闲暇理论以及CFPS数据,从商业养老保险的投保情况与收入情况两个层面实证分析商业养老保险对土地流转的影响。结果显示：商业养老保险一方面通过提高家庭养老保障水平的方式影响家庭参与土地流转的意愿,另一方面通过增加转移收入的方式影响家庭土地流转规模。参保商业养老保险对于土地流转意愿的影响还存在地区差异。     

Socioeconomic predictors of forest use values in the Peruvian Amazon: A potential tool for biodiversity conservation

Conservation is a crisis discipline requiring rapid action with limited funds. This study examines the potential of socioeconomic variables to predict forest use values. If natural resource use can be predicted from socioeconomic data, conservation planners could rapidly identify and focus conservation programs on the sectors of local populations that most intensively utilize local flora and fauna. Families in three communities in the northern Peruvian Amazon were surveyed over a 6-month period. Data were collected on use of flora and fauna from six locally determined use categories (food, medicine and poisons, wood, weavings, adornments, and “other”) in forest types of three age classes (fallow fields—very young forests, young secondary forests, and old secondary forests). Forest use values were the dependant variables calculated in $/ha/year. Socioeconomic variables included: age, education, family size, residence time, land worked, land owned, number of fishing nets, chickens, pigs, cows, and/or mules owned (all proxies for productive assets), and level of ecological knowledge (ability of informants to correctly identify forest species and answer basic questions about their biology). Ordinary least square multiple regressions were run independently for each forest type. Regressions were also run separately for the two most valuable use categories, food and wood. Low R² adjusted values (all < 0.3) reflect the difficulty in predicting human behavior due to confounding variables and complex interactions. Residence time and a household's community of residence were the most significant predictors of forest use values. Households in Vista Alegre, the community with the highest density of people and smallest landholdings per household, extracted the highest value of forest products per hectare. The longer a family stayed in any community the higher the value of forest goods they extracted. If families that lived in an area longest are the most intensive extractors of forest products, they should be a major focus for conservation programming. In addition, the higher value of products extracted from forests by some families may make them more open to strategies seeking to protect long-term viability of the resources they utilize. The importance of residence time also indicates that planners need to account for changes in the resource use patterns of stakeholders over time.     

Is Meta-Analysis a Noah's Ark for Non-Market Valuation?

This paper describes meta-analytical methods as they have been appliedto non-market valuation research. These studies have been used to reviewand synthesize literature and, more recently, in benefit transfer. Thissecond use imposes a higher standard on the consistency in economicconcepts being summarized and in the resources included in ameta-analysis. To meet this need, the paper proposes and illustrates astructural framework using a generalized method of moments estimator toestimate the parameters of a preference function with the benefitsestimates usually encountered in meta-analytic summaries.     

Post OPA-90 Vessel Oil Transfer Spill Prevention: The Effectiveness of Coast Guard Enforcement

Although oil spills from tanker accidents receive the most publicity, most vessel spills are not the result of accidents but of oil transfer activities. We investigate determinants of the size of vessel oil transfer spills as well as the effectiveness of Coast Guard enforcement activities in reducing their size. Vessel out-of-water and in-water oil transfer spillage functions are estimated utilizing tobit regression and detailed data on individual vessel oil transfer spills as well as Coast Guard safety/environmental enforcement activity data for the 1991–1995 period. Our estimation results suggest that Coast Guard hull but not machinery inspections are effective in reducing both out-of-water and in-water spills; patrols by air, but not by boat, are effective in reducing out-of-water spills; but neither is effective in reducing in-water spills. The results also show that the type of vessel (oil- and non-oil-cargo), vessel characteristics, vessel operations, weather/visibility conditions, and waterway type are determinants of post OPA-90 vessel oil transfer spills.     

Evaluating Projects and Assessing Sustainable Development in Imperfect Economies

We are interested in three related questions:(1) How should accounting prices be estimated?(2) How should we evaluate policy change in animperfect economy? (3) How can we check whetherintergenerational well-being will be sustainedalong a projected economic programme? We do notpresume that the economy is convex, nor do weassume that the government optimizes on behalfof its citizens. We show that the same set ofaccounting prices should be used both forpolicy evaluation and for assessing whether ornot intergenerational welfare along a giveneconomic path will be sustained. We also showthat a comprehensive measure of wealth,computed in terms of the accounting prices, canbe used as an index for problems (2) and (3)above. The remainder of the paper is concernedwith rules for estimating the accounting pricesof several specific environmental naturalresources, transacted in a few well knowneconomic institutions.
