纵向财政失衡、FDI竞争与医疗卫生服务供给水平——兼论标尺竞争机制下地区间的策略性行为北大核心CSSCI

关于医疗卫生服务供给不足的原因一直是社会各界高度关注的重点话题,现行的财政分权制度常被认为是最主要的原因。本文尝试将表征现行财政分权制度特征的三个要素,即纵向财政失衡、地区FDI竞争和地区间竞争模仿的策略性行为,与医疗卫生服务供给水平纳入同一分析框架,在对其理论机制分析的基础上,利用2007-2018年277个地级及以上城市面板数据,实证考察它们之间的关系特征及机制路径。研究发现,纵向财政失衡与地区FDI竞争对医疗卫生服务供给水平均存在显著的抑制作用,同时,地区FDI竞争对纵向财政失衡的负向抑制作用具有正向调节效应。进一步分析发现,地方政府间的标尺竞争使其在医疗卫生服务供给行为上表现出明显的策略模仿,医疗卫生服务供给水平呈明显的空间溢出效应。异质性分析发现,发达地区医疗卫生服务供给水平受抑制的主因是FDI竞争所致,欠发达地区则主要缘于纵向财政失衡的显著影响。机制分析发现,纵向财政失衡通过作用于财政支出结构与医疗卫生支出效率两种方式实现对医疗卫生服务供给水平的抑制,而FDI竞争则主要是通过扭曲财政支出结构的方式实现其抑制作用。本文的研究丰富了医疗卫生服务供给不足制度性成因探寻的文献,对于如何全面推进新一轮财税体制改革、深化医疗卫生体制改革、优化政绩考核指标等具有借鉴意义。     

农业供应链金融的数字化转型:理论与中国案例

随着农村电商、物联网和数字金融的快速发展,我国农业供应链金融开始向数字化转型,本文对数字化农业供应链金融模式进行理论和案例分析。研究发现,相比于传统农业供应链金融,数字化农业供应链金融借助于电商平台、物联网、大数据和云计算等数字应用和技术,能够降低金融服务过程中的交易成本,构建农村数字化信用评价体系,优化风险控制策略,最终提高金融供给效率。目前数字化农业供应链金融已形成互联网企业驱动和数字化农业企业驱动两种模式,但是仍面临资金成本高、数字足迹缺乏和信息孤岛等问题,限制其作用的发挥。未来应加快对传统农业的数字化改造,推动农村电商的发展,支持和规范涉农互联网金融机构的发展,最终完善数字化农业供应链金融模式,为发展中国家的农业供应链金融贡献创新模式。     

医疗服务价格管制与"以药养医"

近年来，我国医疗费用持续上涨，医患关系也变得更加紧张。而针对这些问题所采取的一系列改革措施并没有产生明显的效果，这主要是因为没有充分认识到医疗服务价格管制所带来的严重的负面影响。本文提供了一个用于评价医疗服务价格管制的分析框架。本文的分析表明，医疗服务价格管制会导致“以药养医”体制的形成，而且“以药养医”这一间接定价机制，通常无法使患者的效用水平达到只存在道德风险和有限责任约束时的次优水平。因此，改革目前备受非议的医疗体制，重点在于放松对医疗服务价格的管制。     

中国A、B、H股间市场一体化进程研究——基于SKEWED-T-GJR-COPULA方法的实证检验

本文通过构建动态Copula方法,以相依性作为股市间一体化整合指标,考察了1994年至2009年A、B、H股间的一体化进程,发现A股间的一体化基本达到完全整合,两B股间也达到了很高的水平,这两组市场的整合主要在1995年到1997年完成的。A股与B股间一体化程度也较高,其中亚洲金融危机和2001年2月B股改革推动了两市场的整合。而A、B股与H股间的一体化程度相对较低,它们间的整合开始较晚但仍在进行,其中股权分置改革和QDII的实施具有较大的推动作用。另外,中国金融市场如汇率、银行等的改革可能也提高了A、B股与H股的整合速度。

Do Vietnamese upland farmers benefit from high world market prices for maize?

For rural households in the north of Vietnam, maize cropping is the main source of income. In the face of the world market price increases of the recent past, we analyze the regional marketing chain of this commodity qualitatively and econometrically investigating to what extent smallholder farmers in developing countries are affected by international price movements. Vietnamese maize markets are found to be well integrated. Recent price hikes have fully transmitted along the regional supply chain so that farmers profited. Nevertheless, adverse factors such as increasing input prices have neutralized these benefits resulting in a decline in real income of smallholders.     

Country of origin labeling for complex supply chains: the case for labeling the location of different supply chain links

We investigate the value of a country of origin label (COOL) that separately identifies the geographic location of different stages in a food product's supply chain. We estimate the willingness‐to‐pay (WTP) of U.S. consumers for a packaged cereal product where the key grain ingredient may be grown in one country and processed in a second country (multicountry supply chain) and compare it to equivalent products that have both stages located in a single country. We find consumer WTP for products with single‐country and multicountry supply chains are statistically different, meaning that simplifying a multicountry label by listing only the country where the ingredients are grown or only the country where the ingredients are processed can result in different consumer values. We also find that for countries with a poor quality reputation, consumers respond more negatively when that country has the “last touch” than when that country's involvement is limited to upstream supply chain links.     

Prices,institutions, and determinants of supply in the Malian cotton sector

Cotton, both a source of livelihood for millions of poor rural households and a major source of export revenues, is a vital commodity for the economic and social development of Mali. Inefficiencies in the Malian cotton system at the ginnery and producers’ cooperative levels (e.g., late payment to farmers and poorly functioning credit schemes) have recently led to an important decline in supply, threatening the sustainability of the sector. Using regional data from 1998/1999 to 2008/2009, this study aims to quantitatively assess the contribution of key determinants, such as cotton prices and timely payment, toward the downward trend in cotton area. A dynamic supply model, based on adaptive expectations and partial adjustment, is employed to estimate the effects of prices and institutional factors, such as credit recovery rates and date of payment to farmers, on the Malian cotton supply. Results show that supply responds significantly to cotton prices relative to cereal and fertilizer prices. Date of payment varies across agricultural cycles and late payment negatively influences land devoted to cotton. Low credit repayment rates create disincentives to grow cotton. Therefore, the revitalization of the Malian cotton sector depends upon getting both prices and institutions right.

From First Canoe to Statehood: Eight Hundred Years of Economic and Political Change in Hawaii

The Hawaiian archipelago was the last major land area on the planet to be settled, with Polynesians making the long voyage just under a millennium ago. Building on new archaeological and historical research, the lecture provides an overview of the economic and political history of Hawai‘i from the first Polynesian settlements in the thirteen century through U.S. colonisation and statehood. The analysis considers how the political and economic institutions that emerged and evolved in Hawai‘i during its centuries of global isolation changed in response to Hawai‘i's post-1778 integration into a new world of global markets and colonial politics.
