Capturing Inter and Intra Sectoral Productivity Spillovers in Industrial Filière: A System of Dynamic Spatial Panel Data Models
提出一个动态空间面板数据模型系统，同时分析同一地区内不同产业间的溢出效应以及相邻地区间产业内与产业间的生产率溢出，并以意大利农业产业链为例验证了方法的有效性。
ABSTRACT Given the relevance of spatial and sectoral interactions in shaping the productivity performance of economic systems and filières , in this study, we suggest addressing both aspects by estimating a system of simultaneous dynamic spatial panel data models. This approach allows to consider how the production level of a specific sector is influenced by the performance of other interconnected sectors in the same area (cross‐sectoral spillovers) as well as the role of productivity spillovers originating from the same or other sectors in neighbouring territories (inter and intra sectoral spatial effects). The validity of the proposed approach is confirmed through the estimation of a simultaneous system for the production process of the Italian agribusiness filière . The results indicate the existence of meaningful inter‐dependences within and between sectors and territories that materialises in spillovers of different natures (input factors, internal and external features), offering valuable policy implications for the overall economic growth of the agriculture filière .
