【摘要】 市场统一有利于减少资源错配、促进区域经济增长,但跨行政区划的城市间市场统一对域内企业就业的影响及作用机制仍有待检验。文章以长三角经济协调会扩容为一项准自然实验,综合运用2007—2015年全国税收调查数据和2011—2015年中国流动人口动态监测（CMDS）数据考察了市场统一对就业的影响。研究发现,市场统一显著提高了企业的就业吸纳水平,平均提高幅度约为4.22%；在使用PSM—DID、渐进DID等方法进行一系列稳健性检验后,该结论依然成立。市场统一对劳动密集型企业和非重污染企业的就业增加效应更为明显。机制分析表明,市场统一通过缓解融资约束、减少交易成本和降低进入壁垒等渠道降低企业成本,促进企业扩大生产规模和新企业进入,增加劳动力需求；同时,市场统一帮助企业更好地履行了社会责任,提高了企业对劳动者的吸引力。拓展分析表明,市场统一有效提高了青年就业概率,同时也有效提高了劳动收入份额,优化了收入分配格局。文章为市场统一的相关研究补充了来自劳动力市场的新证据,并对在加快建设全国统一大市场进程中更充分地促进高质量充分就业具有启发意义。更多还原

【Abstract】 The resolution of employment predicaments significantly hinges on market dynamism, and market integration is paramount for stimulating such dynamism. Hence, this paper addresses the deficiency in microanalytical perspectives within the context of the current development pattern of “dual circulation” and the concurrent goal of “promoting high-quality full employment”.This paper takes the expansion of the Yangtze River Delta Urban Economic Coordination Council as a quasi-natural experiment and finds that market integration significantly enhances enterprises’ employment absorption capacity. Heterogeneity analysis indicates that labor-intensive enterprises and non-heavy-polluting enterprises exhibit a more pronounced effect in increasing employment. Mechanism testing reveals that market integration reduces enterprise costs through alleviating financing constraints, reducing transaction costs, and lowering entry barriers, thus promoting enterprises to expand production scale and new entrants, thereby increasing labor demand. Meanwhile, market integration facilitates better CSR practices, thereby increasing the attractiveness of enterprises to the labor force. Expansion analysis demonstrates that market integration effectively increases the probability of youth employment while also enhancing the share of labor income.The marginal contributions of this paper are as follows: First, in terms of research perspective, it addresses the deficiency in microanalytical perspectives within the context of the current development pattern of“dual circulation” and the concurrent goal of “promoting high-quality full employment”. Second, in terms of research content, besides examining the impact of market integration on enterprise employment scale, it also investigates the effect on youth employment, wage levels, and the share of labor income, supplementing new evidence from the labor market for relevant studies on market integration. Third, in terms of practical applications, it provides theoretical support for accelerating the construction of a unified national market and more effectively promoting high-quality full employment by drawing on and disseminating the experience of the integration of the Yangtze River Delta.更多还原
