论陕北民间秧歌的现代社会功能

传统陕北秧歌作为一项民俗活动,在演出场面、表演队形、表演风格、采用音乐等方面具有独特的审美形式。传统陕北民间秧歌的现代转型使其同时为民间文化事象和民众活动方式而存在。转型后的现代陕北秧歌在对民众的审美教育和精神团结、行为范导和社会建设等方面具有重要的社会作用。将陕北秧歌作为一种社会资源开发出来,将十分有利于现代和谐这会的建设。

On the Advantage of Quantity Leadership When Outsourcing Production to a Competitive Contract Manufacturer

This study investigates a supply chain comprising an original equipment manufacturer (OEM) and a contract manufacturer (CM), in which the CM acts as both upstream partner and downstream competitor to the OEM. The two parties can engage in one of three Cournot competition games: a simultaneous game, a sequential game with the OEM as the Stackelberg leader, and a sequential game with the CM as the Stackelberg leader. On the basis of these three basic games, this study investigates the two parties' Stackelberg leadership/followership decisions. When the outsourcing quantity and wholesale price are exogenously given, either party may prefer Stackelberg leadership or followership. For example, when the wholesale price or the proportion of production outsourced to the CM is lower than a threshold value, both parties prefer Stackelberg leadership and, consequently, play a simultaneous game in the consumer market. When the outsourcing quantity and wholesale price are decision variables, the competitive CM sets a wholesale price sufficiently low to allow both parties to coexist in the market, and the OEM outsources its entire production to this CM. This study also examines the impact of the supply chain parties' bargaining power on contract outcomes by considering a wholesale price that is determined via the generalized Nash bargaining scheme, finding a Stackelberg equilibrium to be sustained when the CM's degree of bargaining power is great and the non‐competitive CM's wholesale price is high.     

Land‐Price Dynamics and Macroeconomic Fluctuations

We argue that positive co‐movements between land prices and business investment are a driving force behind the broad impact of land‐price dynamics on the macroeconomy. We develop an economic mechanism that captures the co‐movements by incorporating two key features into a DSGE model: We introduce land as a collateral asset in firms' credit constraints, and we identify a shock that drives most of the observed fluctuations in land prices. Our estimates imply that these two features combine to generate an empirically important mechanism that amplifies and propagates macroeconomic fluctuations through the joint dynamics of land prices and business investment.     

数字经济、人工智能制造与劳动力错配

文章基于2013—2019年中国30个省份的面板数据,先运用模拟退火优化投影寻踪模型测算中国数字经济发展指数,再采用双向固定效应模型和广义空间两阶段最小二乘法验证数字经济和人工智能制造对劳动力资源错配的影响效应。结果表明,2013—2019年我国数字经济发展水平整体呈现稳中有进的趋势,年均增速为11.8%。尽管数字经济发展先行区主要位于东部沿海地区,但近年来西部地区各省份年均增速较高,已形成"东部领跑,西部追赶"的空间分异格局。数字经济能显著缓解劳动力错配,人工智能制造在其中发挥着重要的中介作用,这一结论经过稳健性检验后依然成立。
