regressed a linear panel data
we regressed our measures of clustering and reach,and their interaction on
annual firm patent counts using a linear panel data model.
We did so using contemporaneously measured firm patents and one-,two-,and three-year lags of firm patents.

我们回归的衡量聚类和达成,及其交互作用
专利数年公司用线性面板数据模型.
我们这样做使用同时测量,专利和公司,两个-,和3年的滞后于企业专利.
